I’ve been taking Ashwagandha for 7 years on and off.  When you read the research, you start to question what Ashwagandha doesn’t treat.  It’s one of the best all-around supplements for general health.




Withania sominifera (WS) is known commonly as Ashwagandha, Indian ginseng, Poison gooseberry or Winter cherry.  It is a plant of the Solanaceae or nightshade family.

In Sanskrit, Ashwagandha, the Indian name for Withania Sominifera, means “odor of the horse”, probably originating from the odor of its root which resembles that of a sweaty horse [R].

Ashwagandha is also referred to as “Indian ginseng“, since it is used in India, in a way similar to how ginseng is used in traditional Chinese medicine to treat a large variety of human diseases.

In Ayurveda, Ashwagandha is considered a “Rasayana” herb, an elixir that works, in a nonspecific, global fashion, to increase human health and longevity [R].

It is also considered an “Adaptogen“, a nontoxic medication that normalizes physiological functions disturbed by chronic stress, through correction of imbalances in the neuroendocrine and immune systems.

Although used as a broad spectrum remedy in India for centuries, and mentioned as the “Queen of Ayurveda” Ashwagandha has only recently been under investigation in laboratory settings [R].

Traditional Medicinal Uses

In Ayurveda, the fresh roots are sometimes boiled in milk prior to drying to leach out undesirable constituents [R].

The berries are used as a substitute for Rennet, to coagulate milk in cheese making.

Milk supplemented with Ashwagandha has been reported to increase total proteins and body weight.

The Ashwagandha That I Take

Below, I give a bunch of different good options to buy Ashwagandha, but some people want to to know which one I take.


  • Longevity9.1/10
  • Inflammation8/10
  • Mood8.5/10
  • Cognition8.5/10
  • Energy8.6/10


  • Has a wide range of actions and can balance the body in many ways.
  • It stimulates the immune system, while also decreasing inflammation. Few herbs can accomplish this feat.
  • It’s gentle and can be taken daily. Other herbs have a higher potential for side effects.


  • You need to take more than one pill if you want to “feel it.”
  • It doesn’t taste good, so pill form can be better. Smells like horses.
  • Can’t be taken if pregnant, because it may induce abortion.

Buying Ashwagandha: What Joe Uses

Ashwagandha is a very gentle herb, but this also means you likely won’t feel that much with one pill.  I personally need to take a few pills to feel relaxing properties.

The reason there are many different products you can purchase is because there are many types of Ashwagandha that are good.

Withanolides are the most active ingredients, so getting those in a good percentage (2.5% or more) can be good.

The best approach is to try out different brands and see which you do best with. Everyone is different.

Health Tools I Wish I Had When I Was Sick

At SelfHacked, it’s our goal to offer our readers all the tools possible to get optimally healthy. When I was struggling with chronic health issues I felt stuck because I didn’t have any tools to help me get better. I had to spend literally thousands of hours trying to read through studies on pubmed to figure out how the body worked and how to fix it.

    Taking ashwagandh in pills is a waste of time and money. You need the pure dry powder. Anything else is placebo or worse.

  • Greg

    Good article. Big believer in herbal medicine and this helped me a lot. Thankfully I turned down SSRIs offered by my Doctor faster than you can say ashwagandha.
    BE AWARE though that certain herbs must be taken in a certain way. Taking ashwagandha tablets will do very little for two reasons. 1. The quantity is way too small and 2. that’s not how you take it. Ashwandha is properly taken as a heaped teaspoon of dry powder in a small warm glass of milk (with honey, it’s bitter) 3 times a day. The milk has fats that are essential when taking ashwagandha. This applies to quite a few herbs.

    I was diagnosed with hepatitis b two years ago by the Department of Veteran affairs. I experience several symptoms that come and go after a couple of days. Early this year the symptoms came up again and I started Lamivudine, which didn’t help, So I decided to try natural supplements. Three months ago I ordered two bottles of hepatitis b herbal remedy from Best Health Herbal Centre, which I only used for six weeks and the result was extremely marvellous, all symptoms was terminated and my hepatitis b was completely reversed. Thanks to Best Health Herbal Centre, I will never stop sharing my testimony till the whole world know about this wonderful hepatitis b herbal remedy and Am so happy to see myself living hepatitis b negative.

    Hi Joe, I noticed that you recommend the life-extension version which would be the patented sensoril ashwagandha. I would like to know why was there no recommendation for the ksm66 version? Do you believe the sensoril is more Superior? Thank you

  • Cindy

    I started taking NOW brand Ashwagandha last Thursday and have had violent diarrhea ever since… Did not take it yesterday (Thursday) and felt wonderful. Took again today, and again diarrhea, sick stomach, and have thrown up 5 times.. What is the deal? I take in the morning with food…

  • Steven

    Pls can a child of about 22 months be given ashwagandha powder?

  • Sabby

    I have been taking ashwagandha and let me tell you what it does to my body and mind
    Pros : I feel more active mentally and improves concentration ( only mentally not physically active)
    Pros : it balances my male hormones and improves immune system
    Cons : too much stomachache and chest pain
    Cons : bodily movements are less and I feel like sitting on couch
    Not Sure : Libido was normal , sperm quality is good but not the volume of it
    Not Sure : anti – cancer , anti – diabetic or any other benefits mentioned on this website
    Perhaps I will check after 60 days and see if any benefits come

  • M Carol Clifton-DeMott

    I have c677t andhypogammaglobulinemia. I suffered with chronic diarrhea and hypothyroid. I have taken this herb for four months with no diarrhea. I no longer need VSL3, an expensive probiotic and thyroid is now back to normal. I also had muscle wasting before the herb even with lifting weights, now muscles are tightening up. I don’t need IBD guard or Kaopectate. Working great for me!

  • Zette

    I think your article is great and I like the herb a lot. I think I will buy some for my parents. Everyone is different. If the herb is not right for you, QUIT taking it (just like medicines that don’t agree with you, Quit, and try another). Also, you have to change the way you live (your diet, artificial ingredients, etc.), though most people don’t want to change. They just want to take a pill and hope that it works, but you have to change. A lot of info (that I googled ) on Ashwagandha speak of mice studies and that’s why it was shared with the viewers. Love the herb!!! Never written before, but thought it was time.

  • Deepak

    This can be taken in the morning with hot milk right?

  • Tezza

    Me too. This stuff is amazing. It has completely cured me of little niggling concerns such as anxiety, brain fog, insomnia, fibromyalgia, arthritis, slow bowel, weight gain….mmm….sounds like I had a thyroid issue doesn’t it, but tests all came back normal.

  • RD

    The claims above re erectile disfunction are sooooooo misleading. The abstract from the study clearly states that no benefits were found (AKA <25%), and that 19% of the placebo group had an increase in sexual ability compared to the trial group (ashwagandha) which had a 12% increase.

    I would recommend clicking the links for any claim made on this site and reading the abstracts yourself.

    1. Evguenia Alechine

      Hi RD,
      We try our best to check all the references that we include. However, we can make mistakes because we are human. Thank you for your comment, we already fixed the claim that you’re making reference to.

  • Christina

    I was told that Ashwaganda should be avoided if you are prone to hormonal cancers. Is this true because all the research I have been reading is showing the benefits of taking it for cervical cancer? Please advise.

  • An-Marie

    I would like to follow these comments.

  • Jay

    Would there be any interactions with MAOIs (Parnate, Nardil, Marplan etc?

  • AB

    Hi there,
    I am trying to follow Joe’s Lectin avoidance regime plus I am taking the advice that nightshades should be avoided.
    You mention that Ashwaganda is part of the nightshade family. Should this be a concern for the above to issues?

    1. Nattha Wannissorn, PhD

      Joe has no issue with Ashwaganda. Just remove and bring back. That’s the only way to know.

  • Judy

    Hi.I took Ashtawangha to balance my female hormones but it reduced my irritability due to stress and allowed me to sleep well. I had a daily break yesterday after 2 weeks of 500mg dosage for the night. I had headache yesterday and took one pill today in the morning. In 2 weeks I have a big high performance exam and am wondering if I should continue taking the dosage or increase it to 1g. I administered myself this “drug”. Actually Lavandin Oil works similarily on me.Is there any chance that it will improve my mental performance or may it slow me down?
    Please let me know about your experiences. THANKS.

  • Traci

    You’re going to advise the guy to quit taking it without asking him about his dose or anything? Sometimes it takes your body time to adjust.

  • minnymoo69

    I have been taking the Paradise Ashwagandha for 4 days but am finding it is causing extreme fatigue and depression. It does seem to be helping with pain though. Is this fatigue normal? Will it settle down or should I stop taking it.

    Thank you

    1. Nattha Wannissorn, PhD

      No. Don’t take it.

  • Mr. Sick

    I wonder if anyone got an idea, why in some people Ashwagandha doesn’t improve sleep, but gives a person with quite normal sleep insomnia.
    This is what happened to me last week.
    I am really frustrated. I LOVE what this herb is doing for me during the day, but at night it messes up my sleep and counteracts all of the good stuff.
    Unfortunately, I have the same issues with Magnesium and Zinc. At first, they do good and I have positive effects from them, but as the days go by I get more and more insomnia.

    I wonder if those things make too much GABA and this is disrupting my sleep? I read that this could lower Serotonin and thus impair sleep.
    It’s so strange….

    1. Sam Harris

      I have a similar reaction. Spend 200 and get your geneome profiled at 23 and me. See if you have mthfr issues. I do.

      1. Nattha Wannissorn

        You can spend $100 to get the ancestry DNA service at 23andme, and then spend another $19 to run it on SelfDecode. It actually shows you a lot more interesting thing.

      2. Gregor Bellinger

        Thanks for your answer Sam! Would you mind telling me what steps you took to counteract your MTHFR issues? Did you just take Methylfolate?

  • SJWsraiseMommasBoys

    Ashwagandha is awful for anyone with stomach issues. I am sick of seeing fauxperts claim it’s a miracle.

  • Kent White

    Does Ashwagandha need to be cycled (taking a break) in order to maintain effectiveness? If so, what duration? I’ve been taking it all year and actually never want to go off it.

    1. Joseph M. Cohen


  • TH

    “Ashwagandha seems to have some evidence to suggest that it can increase 5-HT2 receptor signalling while reducing 5-HT1A receptor signalling, thus repartitioning serotonin signalling”

    from the examine page, in reference to:

      Interesting 🙂

  • Marck

    Hi Joe,

    It doesn’t relate strictly to this article but more in general.

    I honestly don’t think you should include mice studies in your articles. I mean, if you were actively involved in research you would know that we can cure mice of literally everything from cancer to Alzheimer’s. It’s very misleading to suggests that this actually means anything – because in almost all cases it doesn’t. Despite relatively similar genetics, mice are more and more considered unsuitable model, as many studies which suggest positive effects in mice have no or even negative effects in humans. Ultimately, only human studies matter and you might want to know that many of these mouse studies were probably followed-up in humans but probably didn’t show anything (or showed negative results) and hence were not published!

    I won’t even mention in vitro cell studies as these are almost completely irrelevant unless there is a massively statistically significant effect that can be somehow supported by function hypothesis. Otherwise, taking cells in culture environment and suggesting that the same effect might occur in a complex organism is ridiculous.

    Don’t take it personally but that’s the truth. You might do more harm and good, and I assume you could answer that everybody should experiments for themselves, but… indicating that such things will have any effects is definitely not the way to go.



    1. Joseph M. Cohen

      I appreciate your insights, but I vehemently disagree. Animal studies have been very helpful for giving me leads to try out and be helped by. People can decide for themselves if they want to try something out because of an animal study.

      I am not saying because an animal study says something, it will necessarily work on humans. But it’s enough to experiment with something that’s safe. The only alternative is to not experiment or experiment randomly. The choice is for an individual to make.

    2. Astral Pharoh

      Do you really think these scientist would waste there time and money experimenting on rats if it was useless? Animal studies are not 100% accurate to human studies but there close. I do agree vitro studies are nonsense tho. The fact that you think negative studies don’t get published is ludacris.
