Mimosa For Healing Your Body & Mind

Today weโre looking at mimosa (no relation to the cocktail!), which is a name given to several related plant species that belong to the same genus or general clade, look similar, and have similar properties and behavior.
As a point of interest thatโs not useful: mimosa is one of those plants whereby if you touch it, itโll retract its leaves and shrink away from you. The leaves also droop at nighttime (perfectly healthily; theyโre not wilting or anything; this too is just plant movement), and spring back up in the daytime.
So thatโs what we mean when we say โand behaviorโ ๐
Antidepressant & anxiolytic
Mimosa bark and leaves have long been used in Traditional Chinese Medicine, as well as (albeit different species) in the North-East of Brazil, and (again, sometimes different species) in Mexico.
Animal studies, in vivo studies, and clinical practice in humans, have found this to be effective, for example:
โ[Mimosa pudica extract] has anti-anxiety, anti-depressant and memory enhancing activities that are mediated through multiple mechanismsโ

Research is ongoing with regard to how, exactly, mimosa does what it does. Hereโs a paper about another species mimosa:
(notwithstanding the genus name, itโs still part of the mimosa clade)
Anti-inflammatory & analgesic
In this case, mimosa has traditionally been used as a topical tincture (for skin damage of many kinds, ranging from cuts and abrasions to burns to autoimmune conditions and more), so what does the science say about that?
โIn summary, the present study provided evidence that the [mimosa extract], its fractions and the isolated compound sakuranetin showed significant anti-inflammatory and antinociceptive activitiesโ
Wound healing
About those various skin damages, hereโs another application, and a study showing that it doesnโt just make it feel better, it actually helps it to heal, too:
โTherapeutic effectiveness occurred in all patients of the extract group; after the 8th treatment week, ulcer size was reduced by 92% as mean value in this group, whereas therapeutic effectiveness was observed only in one patient of the control group (chi(2), p=0.0001). No side effects were observed in any patient in either group.โ
Very compelling stats!

Is it safe?
Yes, for most people, with some caveats:
- this one comes with a clear โdonโt take if pregnant or breastfeedingโ warning, as for unknown reasons it has caused a high incidence of fetal abnormalities or fetal death in animal studies.
- while the stem bark (the kind used in most mimosa supplements and most readily found online) has negligible psychoactivity, as do many species of mimosa in general, the root of M. tenuiflora has psychedelic effects similar to ayahuasca if taken orally, for example as a decoction, if in the presence of a monoamine oxidase inhibitor (MAOI), as otherwise MAO would metabolize the psychoactive component in the gut before it can enter the bloodstream.
Thatโs several โifsโ, meaning that the chances of unwanted psychedelic effects are slim if youโre paying attention, but as ever, do check with your doctor/pharmacist to be sure.

Avocado vs Blackberries โ Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing avocado to blackberries, we picked the avocado.
Why?
Both are great and both have their merits! But there is a clear winner:
In terms of macros, avocado has more fiber, protein, and (famously healthy) fats, while blackberries have slightly more carbs; an easy first-round win for avocado.
In the category of vitamins, avocado has more of vitamins B1, B2, B3, B5, B7, B9, E, and K, while blackberries have more of vitamins A and C; another clear win for avocados.
Looking at minerals, avocado has more copper, magnesium, phosphorus, potassium, and zinc, while blackberries have more calcium, iron, and manganese, yielding to avocado a 5:3 win here.
In other considerations, blackberries are higher in polyphenols, so that’s a point in their favor.
Adding up the sections makes for a clear overall win for avocados, but by all means do enjoy either or both, as diversity is best!

Demystifying C-Reactive Protein (CRP)!
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Most people over a certain age who are at least somewhat invested in their health know that c-reactive protein (CRP) is a blood biomarker that’s considered an indicator of cardiovascular health (or: illness, as the case may be), but often know little more than that.
So, what is it and what does it mean?
Oh, CRP
CRP is produced by the liver in response to immune activation from infections, tissue damage, autoimmune disease, obesity, and diabetes.
As for what its actual job is (because the body does produce it for reasons other than for its usefulness as a biomarker in blood tests),
โSimilar to immunoglobulin (Ig)G, it activates complement, binds to Fc receptors and acts as an opsonin for various pathogens. Interaction of CRP with Fc receptors leads to the generation of proinflammatory cytokines that enhance the inflammatory response. Unlike IgG, which specifically recognizes distinct antigenic epitopes, CRP recognizes altered self and foreign molecules based on pattern recognition. Thus, CRP is though to act as a surveillance molecule for altered self and certain pathogens. This recognition provides early defense and leads to a proinflammatory signal and activation of the humoural, adaptive immune system.โ
Source: Function of C-reactive protein
Translating that from sciencese: CRP acts like a first-responder version of an antibody. Like IgG antibodies, it can activate the complement* system, latch onto immune cell receptors, and tag microbes so they are easier for immune cells to destroy. When CRP binds to these receptors, it also triggers the release of inflammatory signals that dial up the immune response.
The key difference is how it recognizes threats: antibodies such as IgG are very specificโthey are custom-made to recognize one precise target and nothing else. CRP, in contrast, looks for broad patterns that signal damage or danger, whether from invading microbes or the bodyโs own altered cells. Thus, CRP acts as an immune surveillance sensor, providing early warning and kick-starting inflammation and the wider adaptive immune response. Which, in the case of an actual infection or similar, is a good thing.
*You may be wondering what, in turn, the complement system is and what activating it means. In simple terms, it starts off as a bunch of proteins circulating in your blood in an inactive form. When CRP (or an antibody) binds to a microbe or a damaged cell, it can activate this cascade, which then joints the fight and also does the latching on and tagging that we mentioned, by:
- directly damaging microbes: in some cases, complement proteins punch holes in bacterial membranes, leading to their death.
- tagging the target for destruction: complement proteins typically coat the surface of the microbe or damaged cell, making it easier for immune cells to recognize and engulf it.
- dialling up inflammation: small complement fragments act like chemical alarms, attracting immune cells and increasing local inflammation.
Again, if there’s actually a genuine threat to respond to, these are all good things for it to be doing.
CRP as a biomarker
CRP is a very useful biomarker of low-grade inflammation, and evidence from decades of research shows it predicts heart attacks and strokes better than LDL cholesterol and lipoprotein(a), and at least as well as blood pressure: Inflammation, Cholesterol, Lipoprotein(a), and 30-Year Cardiovascular Outcomes in Women
Same goes for when we look at mortality: C-reactive protein concentration and risk of coronary heart disease, stroke, and mortality: an individual participant meta-analysis
For this reason, the American College of Cardiology recommended universal CRP screening alongside cholesterol testing to improve cardiovascular risk assessment. You can read that in full, here:
You may be wondering about numbers: CRP under 1 mg/dL indicates low inflammation and lower risk, while CRP above 3 mg/dL signals higher inflammation and higher risk.
How likely is it that you are at risk? Well, about 52% of Americans have elevated CRP, so that’s not a promising figure to start with. Now, 10almonds readers are doubtlessly healthier than the average American as a general demographic, but still, it’s worth bearing in mind and not assuming that it could only apply to other people.
And as for how to improve your numbers? Same deal as most heart health advice that we give here: enjoy a plants-forward (if not entirely plant-based) diet, especially making sure to get a lot of fiber and as many different sources of polyphenols as is reasonable. Get good sleep, do exercise often, and don’t smoke or drink.

Is stress turning my hairย grey?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
When we start to go grey depends a lot on genetics.
Your first grey hairs usually appear anywhere between your twenties and fifties. For men, grey hairs normally start at the temples and sideburns. Women tend to start greying on the hairline, especially at the front.
The most rapid greying usually happens between ages 50 and 60. But does anything we do speed up the process? And is there anything we can do to slow it down?
Youโve probably heard that plucking, dyeing and stress can make your hair go grey โ and that redheads donโt. Hereโs what the science says.
Oksana Klymenko/Shutterstock What gives hair its colour?
Each strand of hair is produced by a hair follicle, a tunnel-like opening in your skin. Follicles contain two different kinds of stem cells:
- keratinocytes, which produce keratin, the protein that makes and regenerates hair strands
- melanocytes, which produce melanin, the pigment that colours your hair and skin.
There are two main types of melanin that determine hair colour. Eumelanin is a black-brown pigment and pheomelanin is a red-yellow pigment.
The amount of the different pigments determines hair colour. Black and brown hair has mostly eumelanin, red hair has the most pheomelanin, and blonde hair has just a small amount of both.
So what makes our hair turn grey?
As we age, itโs normal for cells to become less active. In the hair follicle, this means stem cells produce less melanin โ turning our hair grey โ and less keratin, causing hair thinning and loss.
As less melanin is produced, there is less pigment to give the hair its colour. Grey hair has very little melanin, while white hair has none left.
Unpigmented hair looks grey, white or silver because light reflects off the keratin, which is pale yellow.
Grey hair is thicker, coarser and stiffer than hair with pigment. This is because the shape of the hair follicle becomes irregular as the stem cells change with age.
Interestingly, grey hair also grows faster than pigmented hair, but it uses more energy in the process.
Can stress turn our hair grey?
Yes, stress can cause your hair to turn grey. This happens when oxidative stress damages hair follicles and stem cells and stops them producing melanin.
Oxidative stress is an imbalance of too many damaging free radical chemicals and not enough protective antioxidant chemicals in the body. It can be caused by psychological or emotional stress as well as autoimmune diseases.
Environmental factors such as exposure to UV and pollution, as well as smoking and some drugs, can also play a role.
Melanocytes are more susceptible to damage than keratinocytes because of the complex steps in melanin production. This explains why ageing and stress usually cause hair greying before hair loss.
Scientists have been able to link less pigmented sections of a hair strand to stressful events in a personโs life. In younger people, whose stems cells still produced melanin, colour returned to the hair after the stressful event passed.
4 popular ideas about grey hair โ and what science says
1. Does plucking a grey hair make more grow back in its place?
No. When you pluck a hair, you might notice a small bulb at the end that was attached to your scalp. This is the root. It grows from the hair follicle.
Plucking a hair pulls the root out of the follicle. But the follicle itself is the opening in your skin and canโt be plucked out. Each hair follicle can only grow a single hair.
Itโs possible frequent plucking could make your hair grey earlier, if the cells that produce melanin are damaged or exhausted from too much regrowth.
2. Can my hair can turn grey overnight?
Legend says Marie Antoinetteโs hair went completely white the night before the French queen faced the guillotine โ but this is a myth.
It is not possible for hair to turn grey overnight, as in the legend about Marie Antoinette. Yann Caradec/Wikimedia, CC BY-NC-SA Melanin in hair strands is chemically stable, meaning it canโt transform instantly.
Acute psychological stress does rapidly deplete melanocyte stem cells in mice. But the effect doesnโt show up immediately. Instead, grey hair becomes visible as the strand grows โ at a rate of about 1 cm per month.
Not all hair is in the growing phase at any one time, meaning it canโt all go grey at the same time.
3. Will dyeing make my hair go grey faster?
This depends on the dye.
Temporary and semi-permanent dyes should not cause early greying because they just coat the hair strand without changing its structure. But permanent products cause a chemical reaction with the hair, using an oxidising agent such as hydrogen peroxide.
Accumulation of hydrogen peroxide and other hair dye chemicals in the hair follicle can damage melanocytes and keratinocytes, which can cause greying and hair loss.
4. Is it true redheads donโt go grey?
People with red hair also lose melanin as they age, but differently to those with black or brown hair.
This is because the red-yellow and black-brown pigments are chemically different.
Producing the brown-black pigment eumelanin is more complex and takes more energy, making it more susceptible to damage.
Producing the red-yellow pigment (pheomelanin) causes less oxidative stress, and is more simple. This means it is easier for stem cells to continue to produce pheomelanin, even as they reduce their activity with ageing.
With ageing, red hair tends to fade into strawberry blonde and silvery-white. Grey colour is due to less eumelanin activity, so is more common in those with black and brown hair.
Your genetics determine when youโll start going grey. But you may be able to avoid premature greying by staying healthy, reducing stress and avoiding smoking, too much alcohol and UV exposure.
Eating a healthy diet may also help because vitamin B12, copper, iron, calcium and zinc all influence melanin production and hair pigmentation.

Small Pleasures โ by Ryan Riley

When Hippocrates said “let food be thy medicine, and let medicine be thy food”, he may or may not have had this book in mind.
In terms of healthiness, this one’s not the very most nutritionist-approved recipe book we’ve ever reviewed. It’s not bad, to be clear!
But the physical health aspect is secondary to the mental health aspects, in this one, as you’ll see. And as we say, “mental health is also just health”.
The book is divided into three sections:
- Comfortโfor when you feel at your worst, for when eating is a chore, for when something familiar and reassuring will bring you solace. Here we find flavor and simplicity; pastas, eggs, stews, potato dishes, and the like.
- Restorationโfor when your energy needs reawakening. Here we find flavors fresh and tangy, enlivening and bright. Things to make you feel alive.
- Pleasureโwhile there’s little in the way of health-food here, the author describes the dishes in this section as “a love letter to yourself; they tell you that you’re special as you ready yourself to return to the world”.
And sometimes, just sometimes, we probably all need a little of that.
Bottom line: if you’d like to bring a little more joie de vivre to your cuisine, this book can do that.

Parenting a perfectionist? Hereโs how you can respond
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Some children show signs of perfectionism from early on. Young children might become frustrated and rip up their drawing if itโs not quite right. Older children might avoid or refuse to do homework because theyโre afraid to make a mistake.
Perfectionism can lead to children feeling overwhelmed, angry and frustrated, or sad and withdrawn.
And yet perfectionism isnโt considered all bad in our society. Being called a โperfectionistโ can be a compliment โ code for being a great worker or student, someone who strives to do their best and makes sure all jobs are done well.
These seemingly polarised views reflect the complex nature of perfectionism.
Annie Spratt/Unsplash What is perfectionism?
Researchers often separate perfectionism into two parts:
- perfectionistic strivings: being determined to meet goals and achieve highly
- perfectionistic concerns: worry about being able to meet high standards, and self-criticism about performance.
While perfectionistic strivings can be positive and lead to high achievement, perfectionistic concerns can lead to a higher chance of children developing eating disorders or anxiety and depression, and having lower academic achievement.
Perfectionistic concerns can result in lower academic achievement. Jessica Lewis/Unsplash Children and adolescents may experience perfectionism in relation to school work, sport, performance in art or music, or in relation to their own body.
Signs of perfectionistic concerns in children and adolescents may include:
- children being highly critical of themselves
- their reactions to mistakes seeming to be an overreaction
- intense preoccupation and worry over their standards and goals and/or procrastination
- significant change in performance, for example, lower academic results
- irritability and negative emotions, stress and feelings of worthlessness
- social problems with peers and friends, such as bullying and alienating themselves from peers.
A range of genetic, biological and environmental factors influence perfectionism in children. And as a parent, our role is important. While research evidence suggests we canโt successfully increase positive perfectionistic strivings in our children, harsh or controlling parenting can increase negative perfectionistic concerns in children.
Parents who are perfectionistic themselves can also model this to their children.
So, how can we walk the line between supporting our childโs interests and helping them to achieve their potential, without pressuring them and increasing the risk of negative outcomes?
Give them space to grow
A great metaphor is the gardener versus the carpenter described by psychology professor Alison Gopnik.
Instead of trying to build and shape our children by controlling them and their environment (like a carpenter), parents can embrace the spirit of the gardener โ providing lots of space for children to grow in their own direction, and nourishing them with love, respect and trust.
Parents donโt need to control their child and their environment. Noah Silliman/Unsplash We canโt control who they become, so itโs better to sit back, enjoy the ride, and look forward to watching the person they grow into.
However, there is still plenty we can do as parents if our child is showing signs of perfectionism. We can role model to our children how to set realistic goals and be flexible when things change or go wrong, help our children manage stress and negative emotions, and create healthy balance in our family daily routine.
Set realistic goals
People with perfectionistic tendencies will often set unattainable goals. We can support the development of flexibility and realistic goal setting by asking curious questions, for example, โwhat would you need to do to get one small step closer to this goal?โ Identifying upper and lower limits for goals is also helpful.
If your child is fixed on a high score at school, for example, set that as the โupper limitโ and then support them to identify a โlower limitโ they would find acceptable, even if they are less happy with the outcome.
This strategy may take time and practice to widen the gap between the two, but is useful to create flexibility over time.
If a goal is performance-based and the outcome cannot be guaranteed (for example, a sporting competition), encourage your child to set a personal goal they have more control over.
Parents can help children set goals they can achieve. liz99/Unsplash We can also have conversations about perfectionism from early on, and explain that everyone makes mistakes. In fact, itโs great to model this to our children โ talking about our own mistakes and feelings, to show them that we ourselves are not perfect.
Talk aloud practices can help children to see that we โwalk the walkโ. For example, if you burn dinner you could reflect:
Iโm disappointed because I put time and effort into that and it didnโt turn out as I expected. But we all make mistakes. I donโt get things right every time.
Manage stress and negative emotions
Some children and adolescents have a natural tendency towards perfectionism. Rather than trying to control their behaviour, we can provide gentle, loving support.
When our child or adolescent becomes frustrated, angry, sad or overwhelmed, we support them best by helping them to name, express and validate all of their emotions.
Parents may fear that acknowledging their childโs negative emotions will make the emotions worse, but the opposite is true.
Creating healthy balance
The building blocks of healthy child development are strong loving family relationships, good nutrition, creative play and plenty of physical activity, sleep and rest.
Perfectionism is associated with rigidity, and thinking that there is only one correct way to succeed. We can instead encourage flexibility and creativity in children.
Childrenโs brains grow through play. There is strong research evidence showing that creative, child-led play is associated with higher emotion regulation skills, and a range of cognitive skills, including problem-solving, memory, planning, flexibility and decision-making.
Play helps childrenโs brains grow. Mi Pham/Unsplash Play isnโt just for young children either โ thereโs evidence that explorative, creative play of any kind also benefits adolescents and adults.
There is also evidence that getting active outdoors in nature can promote childrenโs coping skills, emotion regulation and cognitive development.

Moringa Oleifera Against CVD, Diabetes, Alzheimer’s & Arsenic?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
The Healthiest Drumstick
Moringa oleifera is a tree, whose leaves and pods have medicinal properties (as well as simply being very high in nutrients). Itโs also called the drumstick tree in English, but equally often itโs referred to simply as Moringa. It has enjoyed use in traditional medicine for thousands of years, and its many benefits have caught scientistsโ attention more recently. For an overview before we begin, see:
Now, letโs break it downโฆ
Anti-inflammatory
It is full of antioxidants, which weโll come to shortly, and they have abundant anti-inflammatory effects. Research into these so far has mostly beennon-human animal studies or else in vitro, hence the guarded โpotentialโ for now:
Potential anti-inflammatory phenolic glycosides from the medicinal plant Moringa oleifera fruits
Speaking of potential though, it has been found to also reduce neuroinflammation specifically, which is good, because not every anti-inflammatory agent does that:
Antioxidant
It was hard to find studies that talked about its antioxidant powers that didnโt also add โand this, and this, and thisโ because of all its knock-on benefits, for example:
โThe results indicate that this plant possesses antioxidant, hypolipidaemic and antiatherosclerotic activities and has therapeutic potential for the prevention of cardiovascular diseases.
These effects were at degrees comparable to those of simvastatin.โ
~ Dr. Pilaipark Chumark et al.
Likely a lot of its benefits in these regards come from the plantโs very high quercetin content, because quercetin does that too:
Quercetin reduces blood pressure in hypertensive subjects
For more about quercetin, you might like our previous main feature:
Fight Inflammation & Protect Your Brain, With Quercetin
Antidiabetic
It also has been found to lower fasting blood sugar levels by 13.5%:
Anti-arsenic?
We put a question mark there, because studies into this have only been done with non-human animals such as mice and rats so far, largely because there are not many human volunteers willing to sign up for arsenic poisoning (and no ethics board would pass it anyway).
However, as arsenic contamination in some foods (such as rice) is a big concern, this is very promising. Here are some example studies, with mice and rats respectively:
- Protective effects of Moringa oleifera Lam. leaves against arsenic-induced toxicity in mice
- Therapeutic effects of Moringa oleifera on arsenic-induced toxicity in rats
Is it safe?
A popular food product through parts of Africa and (especially) South & West Asia, it has a very good safety profile. Generally the only health-related criticism of it is that it contains some anti-nutrients (that hinder bioavailability of its nutrients), but the nutrients outweigh the antinutrients sufficiently to render this a trifling trivium.
In short: as ever, do check with your doctor/pharmacist to be sure, but in general terms, this is about as safe as most vegan whole foods; it just happens to also be something of a superfood, which puts it into the โnutraceuticalโ category. See also:
