Erectile dysfunction (ED) is a common condition. The National Institute of Diabetes and Digestive and Kidney Diseases estimates that ED affects 30 million men in the United States. It has various causes, including physical factors and emotional conditions such as stress and anxiety.

While several medications are available to treat ED, many people may prefer to use natural methods and herbal supplements. One such supplement that you may have heard of is ashwagandha.

This popular Ayurvedic herb has various benefits and may help to improve mental health, sleep quality, and athletic performance. Ashwagandha may also have a positive impact on male sexual health.

Ashwagandha is a type of herb that grows naturally in India and Southeast Asia. It’s often used in Ayurvedic medicine.

You may also see ashwagandha called Indian ginseng or winter cherry. Its scientific name is Withania somnifera.

Typically, the root of the plant is used in Ayurvedic medicine. However, the leaves and flowers can be used as well.

Extracts of ashwagandha can have as many as 35 different chemical components. So far, a specific active ingredient hasn’t been determined.

Ashwagandha is used in Ayurvedic medicine as a Rasayana, or a type of therapeutic preparation that’s used to boost general health, increase energy levels, and promote longevity.

Ashwagandha is considered an aphrodisiac, or herb used to improve sexual desire, pleasure, or performance. While scientific research doesn’t support the herb’s use for ED, it may be effective for low libido.

Overall, a very limited amount of research has been carried out on the effectiveness of ashwagandha for ED. Let’s examine what it says so far.

A study from 2002 looked at the effect that an ashwagandha extract had on male rats over a week. The researchers found that the rats actually experienced increased ED as well as lower sex drive and performance.

A study from 2011 investigated the use of ashwagandha for a specific type of ED called psychogenic ED, which is primarily associated with sexual anxiety and worries about sexual performance.

In the study, 86 men with psychogenic ED received either ashwagandha or a placebo for 60 days. Overall, ashwagandha didn’t provide any more relief for ED than the placebo. A 2014 follow-up analysis by the same research group confirmed these findings.

Avoid taking ashwagandha if you:

  • Are pregnant or breastfeeding. Ashwagandha in high doses may be harmful to a developing fetus. There are currently no studies available on the safety of ashwagandha while breastfeeding.
  • Are taking sedatives. Since ashwagandha itself is sometimes used as a sedative, avoid using it if you’re taking medications like benzodiazepines, barbiturates, or anticonvulsants.

Traditionally, ashwagandha is prepared as a powder. You’d then use this powder to make a tonic that you’d drink.

Ayurveda is an ancient Indian medical practice that combines dietary and lifestyle practices with natural therapies. It aims to promote health and longevity by achieving balance in the environment and the mind, body, and spirit.

Vajikarana and ED

There are eight different domains in Ayurveda. Each domain focuses on a different area of health. Conditions like ED are addressed under the domain of Vajikarana, which centers on sexual health and reproduction.

Vajikarana uses a variety of formulations that aim to enhance sexual function. These formulations can have a variety of different natural ingredients and are believed to work by acting on the brain’s hypothalamus and limbic system.

Some Vajikarana formulations can include ashwagandha. Additional examples of plants that may be used in Vajikarana are:

  • Saccharum officinarum, a kind of sugarcane
  • Piper longum, a variety of pepper
  • Mucuna pruriens, a tropical bean
  • Asparagus racemosus, a variety of asparagus
  • Pueraria tuberosa, a type of kudzu

Other supplements for ED

There are other herbal supplements that may be beneficial for ED. These include Panax ginseng and Pausinystalia yohimbe. More research is needed to show evidence of their effectiveness, side effects, and safety.

Unlike drugs, supplements don’t require Food and Drug Administration (FDA) approval. Because of this, they may not undergo rigorous testing to determine their safety and effectiveness.

Follow the tips below while shopping for ashwagandha or any other dietary supplement:

  • Verify the name. Make sure the name on the product label matches what you’re looking for. In addition to ashwagandha, the label could say Withania somnifera or Indian ginseng.
  • Check the ingredients. The label should list all of the ingredients in a supplement. If you’re unsure about what an ingredient is, ask a doctor or pharmacist. You can also look up ingredients using the Dietary Supplement Label Database maintained by the National Institutes of Health.
  • Beware of claims. Be wary of any product claims that seem too good to be true or say they can treat a specific medical condition.
  • Do your own research. Obtain your own information using reputable sources. One place to start is PubMed, a great resource for scientific studies. You may also find the National Center for Complementary and Integrative Health to be a helpful source of information.
  • Look for seals and certificates. While supplements aren’t regulated for standards by an independent body, some companies can verify their products’ content by having them tested in an independent lab. Look for a seal from a third-party organization like NSF International and USP.

What is the best dosage of ashwagandha?

Ashwagandha dosage varies depending on which condition you’re trying to manage. Daily doses may range from 125 milligrams to 5 grams. You can take equal doses 1 to 3 times per day.

The typical ashwagandha dosage for reproductive health is around 5 grams per day. Since dosages may vary between products, follow the manufacturer’s recommendations or consult your healthcare professional for guidance.

Is ashwagandha comparable to Viagra?

Ashwagandha is different from Viagra. Viagra is a prescription drug specifically designed to treat ED in adults. Ashwagandha is an adaptogenic herb, meaning it may help your body bounce back from stress.

Ashwagandha has several health benefits and may enhance certain aspects of sexual health. However, quality research supporting its effectiveness for ED is lacking.

What’s more, you need to take ashwagandha daily for at least 1 month to see results. You only need to take Viagra when you need it, and it usually starts working within 1 hour.

Can my doctor prescribe me ashwagandha?

No, your doctor cannot prescribe ashwagandha. You can purchase the herbal supplement online or in health food stores. However, it’s important to talk with your doctor before using ashwagandha, especially if you have a health condition or take medications or supplements. They may recommend an appropriate dosage and a reputable brand.

Ashwagandha is an herb that’s used as part of Ayurvedic medicine. Research has indicated that it may have several health benefits, such as lowering anxiety, promoting better sleep, and decreasing inflammation.

While ashwagandha is considered an aphrodisiac, scientific research doesn’t currently support its use for ED.

Ashwagandha is generally safe and has few serious side effects. If you’re considering ashwagandha as a supplement, discuss its potential benefits and risks with your doctor before using it.
