The 6 Anti-aging Plant Extracts Scientists Say Prolong Life

You need to know about the 6 anti-aging plant extracts that scientists used to substantially extend the life of yeast, and why they should be part of your diet too.

6 Anti-aging plant extracts you can use now

THE INTERNET has been buzzing with some interesting anti-aging news of late over a study published in the online journal, Oncotarget, about plant extracts that greatly delay the chronological aging of yeast.

What do slow-aging yeast have to do with you, and just which anti-aging plant extracts are we talking about here, you ask?

Well, grasshopper, these are just two of several tantalizing questions answered in this article. Read on and find out what you should be adding to your diet to improve your health over the long run, so says science.

In this article, you'll discover:

  • The 4 major anti-aging mechanisms the 6 plant extracts activate;
  • Why studying these effects on yeast are useful to humans;
  • The names of the 6 anti-aging plant extracts and how you can use them; and
  • The 2 Indian herbs you can add to make you age-proof (kinda).

 

The Anti-aging Plant Extract Study’s Big Four Conclusions

Let’s start with what the scientists discovered, per the Oncotarget abstract:

  1. They discovered six plant extracts that increase yeast chronological lifespan to a significantly greater extent than any of the presently known longevity-extending chemical compounds.
  2. One of these extracts is the most potent longevity-extending pharmacological intervention yet described.
  3. They show that each of the six plant extracts is a geroprotector, which delays the onset and decreases the rate of yeast chronological aging by eliciting a hormetic stress response. (See the graph below.)
  4. They also show that each of these extracts has different effects on cellular processes that define longevity, which include:
    • Increased mitochondrial respiration and membrane potential;
    • Augmented or reduced concentrations of reactive oxygen species;
    • Decreased oxidative damage to cellular proteins, membrane lipids, and mitochondrial and nuclear genomes;
    • Enhanced cell resistance to oxidative and thermal stresses; and
    • Accelerated degradation of neutral lipids deposited in lipid droplets. Our findings provide new insights into mechanisms through which chemicals extracted from certain plants can slow biological aging.

Now to the four statements presented above and how they’re relevant to your quest to live a long and healthy life, even though you’re not, presumably, yeast.

Statement #1, Yeast and Anti-aging Plant Extracts

Yeast cells were used in the experiment, because their aging rate is similar to that of human cells. In fact, most metabolic and cellular pathways thought to occur in humans can be studied in yeast.

This is true despite your spot-on perception that you’re not one of these single-celled microorganisms; yet, strangely, we humans share some important biological similarities with yeast. For instance, an important feature of yeast that make them such useful organisms for studying biological processes in humans is that their cells, like ours, have a nucleus containing DNA packaged into chromosomes.

(More about yeast and humans here.)

What this distills down to is that scientist can infer that the effects of certain biochemical manipulations on yeast might pertain to humans as well. So when it’s discovered that certain plant extracts measurably extend the lifespan of yeast, scientists get all giddy-like, because they think it could also be true for us brainy bipeds.

Statement #2, The Most Potent Extract

I’ll just tell you straight away that the most potent extract the researcher found among the six is White Willow Tree extract. It was the only one mentioned in several of the articles I read about this study. For some reason, none of the other five were mentioned, till I dug deeper. More on that below.

Statement #3, Geroprotection and Hormesis

The next thing you might be wondering about is what the heck is a “geroprotector”?

That’s a new word for me, too, so I looked it up and immediately liked it. I want one. Maybe several.

According to Wikipedia,

a “geroproctector” is a senotherapeutic (therapeutic agents and strategies that specifically target cells that no longer can divide) that aims to affect the root cause of aging and age-related diseases, and thus prolong the life span of animals. Some possible geroprotectors include melatonin, carnosine, metformin and delta sleep-inducing peptide (short-chain amino acids that induces deep sleep).

(Don’t go before reading about Metformin.)

So, what the plant-extract study reveals is that the extracts affected some of the basic causes of aging, and did so by stimulating a hormetic stress response.

Which then begs the question, “What’s a ‘hormetic stress response’”?

To answer that, let’s turn to hormesis expert and blogger, Todd Becker, who on his thoroughly enjoyable and insightful blog, Getting Stronger, writes:

“Hormesis is a biological phenomenon whereby a beneficial effect (improved health, stress tolerance, growth or longevity) results from exposure to low doses of an agent that is otherwise toxic or lethal when given at higher doses.”

The following graph presents the conceptual understanding that some things (chemicals, foods, drinks) can either be beneficial to an organism (like you) or harmful depending on the dose.  This reminds me of prevailing consensus that one glass of red wine per day is good, but a case of it is toxic.

 

Get stronger thru the process of hormesis

Hormesis postulates that low doses of ROS (“Reactive Oxygen Species”) are beneficial and have a physiologic role, while increasing doses (yellow line) will cause toxicity. This is in contrast to the traditional view that all levels of ROS (dotted line) will have a harmful effect.

Statement #4, The Biological Processes Pertinent to Longevity (or the lack thereof)

This part gets into the nitty gritty of several of the reasons that aging happens. The chemicals extracted from certain plant extracts apparently slow-down biological aging by:

  • Increasing the capacity of the part of the cell (mitochondria) where the biochemical processes of respiration (converting macronutrients to energy) and energy production occur;
  • Harmonizing the production of oxidative stress (reactive oxygen species) and thermal stress to levels most suitable to longevity; and
  • The biosynthesis, storage and lipolysis of neutral lipids that emergent evidence suggests are longevity assurance processes.

(Read the study for details.)

 

How The Study Was Done

As mentioned, scientists learned how to slow the chronological age of yeast in lab experiments. They did the study at Concordia University and Idunn Technologies, and published in the journal Oncotarget.

Using six plant extracts, they decelerated the aging process in samples of yeast more so than any other experiment tried before. The researchers discovered compounds that inhibit the yeast’s pro-aging pathways and proteins. Although no human trials have commenced, the same anti-aging plant extracts used in the yeast experiments are available on the market in supplement form, as I’ll show you later.

Yeast cells were used in the experiment, because their aging rate is similar to that of human cells. The wild yeast strain Saccharomyces cerevisiae was cultured in flasks at a temperature of 30 degrees Celsius. The plant extracts were added one at a time with 2% glucose into the yeast cultures.

The scientists then monitored the rate of chronological aging in the yeast as they responded to each plant extract. This process was measured at the cellular level.

Scientists were measuring pro-aging and anti-aging processes. Each plant extract gave different readings, but the extract from the White Willow tree (Salix alba) was the most potent at slowing the aging process down in the cultured yeast.

According to Worldhealth.net, lead researcher and senior author of the study, Vladimir Titorenko, says the

yeast have nutrient-sensing pathways that accelerate their aging under normal growth conditions. The chemical compounds in the anti-aging plant extracts obstruct these pathway signals and are responsible for the measured delay in aging of the yeast.

The most surprising observation was that human post-mitotic cells (those no longer capable of mitosis; basically, division of the nucleus) are also affected by similar nutrient sensing pathways, suggesting that pharmaceutical manipulation of these beneficial plant compounds may lead to decelerating old age and diseases in humans.

(I say, forget about waiting for the drug companies… I want those plant extracts now, which I’ll be getting to below.)

Éric SimardCo-author of the study Éric Simard hypothesized that inhibiting the pathways of post-mitotic cells in humans could delay and slow the growth of many chronic diseases. Some of the diseases noted include heart disease, diabetes, arthritis, Alzheimer’s, Parkinson’s, stroke, and cancer.

Titorenko explained that the six extracts used to slow aging in yeast, are commercially available and approved for human consumption by Health Canada. Five of the extracts have been approved for use in health supplements.

But nobody in the Worldhealth article, or in several others divulged what these extracts are. They did, however, identify the yeast strain and the six extracts.

The yeast strain used in the experiments:

  • Saccharomyces cerevisiae

Six extracts were obtained from the following plant groups:

  • Cimicifuga racemosa
  • Valeriana officinalis
  • Passiflora incarnata
  • Ginkgo biloba
  • Apium graveolens L. 
  • Salix alba

Kinda worthless info if what you want to do is go on Amazon.com and buy some anti-aging plant extracts.

So, as mentioned, I had to dig some more, and eventually I found two articles that listed the anti-aging plant extracts I sought, Plant Extracts Slow Yeast Aging, Could Work in Humans and 6 Plants That Can Extend Your Life.

 

The Six Anti-aging Plants Extracts

Without further adieu, here’s the six plants described in the Life Extension Foundation article whose extracts may just be able to tickle a few more healthy years of life out of you, whether you’re yeast or not:

  1. White Willow Bark is associated with the strongest life extension effect among the six extracts. White willow bark is a source of salicylic acid which, when synthesized, gives us the anti-inflammatory pain reliever known as aspirin, that has been associated with remarkable benefits, including protective effects against cancer and cardiovascular disease. Salicylic acid targets a protein known as HMGB1, which is associated with rheumatoid arthritis, heart disease, sepsis and inflammation-associated cancers, leading some researchers to suggest that the compound be called “vitamin S,” due to its tremendous benefits.
  2. Black Cohosh is a common ingredient in formulas designed to support menopause and perimenopause, due to its estrogenic action.
  3. Valerian Root has been used for many years to bring on and ensure sound sleep. A recent trial found valerian superior to a placebo in maintaining postoperative cognitive function, which is often impaired during the weeks following certain procedures. The researchers attribute valerian’s benefit to its anti-inflammatory property and ability to stimulate serotonin receptors.
  4. Purple Passion Flower is also used to induce calmness and sleep. It is a source of the flavone chrysin. In addition to other properties, chrysin reduces the conversion of testosterone to estrogen, which enhances free testosterone levels.
  5. Ginkgo Biloba is a popular herb, particularly for the enhancement of cognitive function. In 2002, a standardized extract of ginkgo leaves extended the life span of C. elegans by an average of 8%, while increasing their resistance to oxidative stress.7 When components of the extract were tested, a flavonoid known as tamarixetin was found to extend median life span by an average of 25%.Other research has found that ginkgo protects against age-associated oxidative damage to mitochondrial DNA.
  6. Celery is, of course, known to all. The vegetable is a good source of apigenin, which has anti-inflammatory and anticarcinogenic properties. Apigenin has been shown to improve neuron formation and connectivity. Celery additionally contains the flavonoid luteolin, which also has anti-inflammatory and neuroprotective effects.

Now the question ping ponging around in my mind is,

“Just what is a plant extract in this instance?”

I’m unsure, but what I know it’s not is these plants themselves in their natural form, as in pluck it out of the ground (or off the tree) and start chewing. Instead, it makes sense that the extract is the powdered form of the plant, either in capsules or powders, or distilled into tinctures.

What follows are links to an assortment of brands from each of the six plant extracts. My suggestion is to choose the extract form that you’re most likely to use.

Given that I consume a smoothie on most days (see below), my preference is to get the extracts in powder form and add each to my drink. A close second for me would be to use the tinctures — they could easily be dropped into a warm glass of pure water each morning.

How Much To Take?

What we don’t know from the anti-aging plant extract study is what dosage to take.  We’re really ahead of the curve here, given that human studies haven’t been done. I suggest you begin with some fraction of the dosage suggested on the label of each extract, and slowly increase it until you’re consuming the amount on the label.

 

Get Calm and Insulin-sensitive with Ashwaganda and Amla

Frequent readers know that I’m a fan of the Indian herbs, Ashwagandha and Amla. I wrote about Ashwagnadha at length in More Muscle, Testosterone and Calm with Ashwagandha.

There’s much to know about Ashwagandha, and I encourage you to read the article, and consider adding it to the plant extracts you consume.  Here’s a snippet:

Herbs like Ashwagandha are called adaptogens because of their unusual ability to “adapt” their function according to our bodies’ specific needs. It’s subtle and may take a month or so, but after a while it dawns on you that you’re somehow feeling better about things, less frantic — that all is fine in the world.

Amla is also called “Indian Gooseberries” and can work better than pharmaceuticals to lower blood sugar, as can several other supplements that I wrote about in Eight Steps To Get More Sex and A Longer Life By Supercharging Your Blood.

On his site NutritionFacts.org, nutritional expert Dr. Michael Greger says this about Amla/Indian Gooseberry:

Am I recommending people treat their diabetes with gooseberry powder? No, I recommend curing your diabetes… Why treat anything when you get at the root cause and reverse it in the first place.

In his book, How Not To Die, Dr. Greger got almost giddy, it seems, writing about his use (and seeming affection) for Amla:

“The standard American diet (SAD) isn’t exactly antioxidant packed. Here is the antioxidant content (in modified FRAP assay daμmol antioxidant units) of some typical American breakfast foods: bacon (7) and eggs (8), a bowl of corn flakes (25) with milk (10), an Egg McMuffin (11), pancakes (21) with maple syrup (9), and a bagel (20) with cream cheese (4). A typical breakfast may average about 25 antioxidant units.

“Compare those to the smoothie I had for breakfast this morning. I started with a cup of water (0), a half cup of frozen blueberries (323), and the pulp of a ripe mango (108). I added a tablespoon of ground flaxseeds (8), along with a half cup of fresh mint leaves (33) and a palmful of bulk white tea leaves (103).

“While the typical SAD breakfast may give you only about 25 antioxidant units, my breakfast smoothie offered more than 500. And, when I add the final ingredient, a single teaspoon of amla, I get an additional 753 antioxidant units. That’s about four cents’ worth of amla, and it just doubled the antioxidant content of my entire smoothie. Before I’ve even fully woken up, I’ve already consumed more than 1,000 antioxidant units. That’s more than the average person may get in an entire week. I could drink my smoothie and eat nothing but doughnuts for the rest of the week, and most people still wouldn’t catch up. Notice that even though I packed the blender with amazing foods like blueberries and tea leaves, fully half the antioxidant power came from that single, four-cent teaspoon of powdered gooseberries.”

Even if you eat a diet aimed at maintaining insulin sensitivity and thus rarely eat high glycemic carbs that spike blood sugar (like fruit juice, potatoes, processed grains), your blood sugar will naturally increase as you age (along with a corresponding desensitivity of insulin, meaning that your pancreas has to pump out more), as this graph indicates:

Blood sugar increases with age, as does diabetes.

A Longevity-packed Smoothie

Dr. Micheal Greger shared his smoothie recipe and I’ll do the same.

The ingredients in my smoothie vary, given that I cycle in and out of herbs/supplements.  Lately, here’s what’s in it:

Use the amounts you prefer or what’s suggested on the labels.  The amount of liquid will either make it watery or thick. The veggies and blueberries are either fresh or frozen.  I suggest you begin with just a few ingredients and add more as you become accustomed to it.

My intention is to add the six plant extracts.

 

Your Takeaway

Before you click away, remember these four takeaways about the anti-aging plant extract study:

  1. Scientists have discovered six plant extracts that substantially increase the longevity and vitality of yeast.
  2. Although you are not yeast, their aging rate is similar to that of human cells, which why they’re used in aging studies.
  3. These plant extracts have been identified, but we do not know how much to take, nor if they will really be useful in prolonging human lifespan.  That said, we do know that these plant extracts do convey specific health benefits if regularly consumed.
  4. Two recommended ways to ingest the plant extracts is via powders added to smoothies or tinctures added to warm water.

This information is most valuable so wanted to thank you for digging it up for us. Don’t know why we are given so little information with which to help ourselves, when those studies are done, but am guessing perhaps the drug companies want to get paid for their longevity pills so we get a tease of what’s to come.

Am already doing the Metformin, while never having had diabetes, and am wondering if taking low dose aspirin synthetic salicylic acid is as effective as white WILLOW bark salicylic acid because I have also been taking the aspirins and would prefer to not switch. So what’s the difference?

Once more thanks as I tried discovering how to use the scant information from the studies and was unable to get anywhere. Kudos to you Joe!

Angele, don’t know how the Willow Bark salicylic acid compares to that in aspirin, but would guess that there are synergistic effects offered by the actual plant that the synthetic can’t offer. I also take a low-dose aspirin, 81 mgs, at bedtime, but intend to use the Willow Bark instead once I add it and the others to my regimen.

Update for Angele…

Did some looking around for concrete reasons Willow Bark is preferential to aspirin and found this written by Dr. Rhonda Patrick: https://www.foundmyfitness.com/news/stories/rn6ivz The net of it is that it’s better to get salicylic acid from Willow Bark than from Aspirin.

Is there a course, like 1, 2, 4, 6 months that is recommended for daily ingestion of these extracts and, then, how long would it be suggested you wait to add them back into your diet again?

Reply
Joe Garma - September 25, 2016

Marc, it’s pretty much all guess work when it comes to applying the study’s regimen to humans, given that the study outlined here was done w/ yeast: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4941334/. Typically, herbs should be rotated in and out of a person’s diet for best results, but I’m unclear of a precise formula for the time frames on and off. In my case, I usually stay on a herb for about three months and then put it aside for one month. My plan for these herbs is to either get powders or tinctures and use them together, three months on, one off.
