Who Should Not Take Ashwagandha: Precautions and Contraindications
Ashwagandha is a traditional Ayurvedic medicine that has been used for centuries to promote physical and mental wellness. It has gained immense popularity recently due to its potential health benefits, such as reducing stress, anxiety, and inflammation, and improving brain function and fertility. However, like any other supplement or medication, ashwagandha may not suit everyone, and there are certain precautions and contraindications that need to be considered before using it.
What is Ashwagandha and How Does it Work?
Ashwagandha, also known as Withania somnifera, is a herb that belongs to the Solanaceae family and is native to India. Its root and leaves are used in various forms, such as powders, extracts, capsules, and teas, for medicinal purposes.
Ashwagandha contains several bioactive compounds that give it its therapeutic properties, such as withanolides, alkaloids, and flavonoids. It works by modulating the activity of various neurotransmitters, hormones, and enzymes in the body, which helps to reduce stress, improve cognitive function, boost immunity, and regulate metabolism. It also has antioxidant and anti-inflammatory properties that protect the body against cell damage and oxidative stress.
Recent studies have also shown that ashwagandha may have potential benefits for people with anxiety and depression. It has been found to reduce symptoms of anxiety and improve mood by regulating the levels of cortisol, a stress hormone, in the body. Additionally, ashwagandha has been shown to increase the levels of GABA, a neurotransmitter that helps to calm the brain and reduce anxiety. These findings suggest that ashwagandha may be a natural and effective alternative to traditional anti-anxiety and antidepressant medications.
Benefits of Ashwagandha for Health and Wellness
Ashwagandha has been studied extensively for its potential health benefits, and some of the most promising ones are:
- Reducing stress and anxiety: Ashwagandha is known to reduce cortisol levels in the body, which is a hormone that is released in response to stress. This helps to promote relaxation and reduce anxiety and depression symptoms.
- Improving brain function: Ashwagandha has been shown to improve memory, attention, and cognitive performance in adults with mild cognitive impairment and dementia.
- Boosting immunity: Ashwagandha has immunomodulatory effects that help to enhance the activity of natural killer cells and increase the production of antibodies in the body, which helps to fight infections and diseases.
- Reducing inflammation: Ashwagandha has anti-inflammatory properties that help to reduce inflammation markers in the body and alleviate symptoms of conditions like arthritis and asthma.
- Enhancing fertility: Ashwagandha has been shown to improve sperm count and motility in men and regulate menstrual cycles and hormone levels in women.
In addition to the above benefits, Ashwagandha has also been found to have anti-cancer properties. Studies have shown that Ashwagandha extract can inhibit the growth of cancer cells and induce apoptosis (programmed cell death) in various types of cancer, including breast, lung, colon, and ovarian cancer. However, more research is needed to fully understand the potential of Ashwagandha as a cancer treatment.
Understanding Precautions and Contraindications for Ashwagandha Use
While ashwagandha is generally safe for most people, there are certain precautions and contraindications that need to be considered before using it. Some of these are:
- Allergies: People who are allergic to plants in the Solanaceae family, such as tomatoes, potatoes, and eggplants, may also be allergic to ashwagandha and should avoid using it.
- Autoimmune diseases: Ashwagandha may stimulate the immune system, which can worsen autoimmune diseases like multiple sclerosis, lupus, and rheumatoid arthritis.
- Hypoglycemia: Ashwagandha may lower blood sugar levels, which can be dangerous for people with hypoglycemia or diabetes who are already taking medications to control their blood sugar.
- Thyroid disorders: Ashwagandha may increase thyroid hormone levels, which can be problematic for people with hyperthyroidism or those who are taking thyroid medications.
- Surgery: Ashwagandha may have sedative effects and interact with anesthesia, so it should be avoided at least two weeks before surgery.
It is important to note that ashwagandha may also interact with certain medications, such as sedatives, antidepressants, and immunosuppressants. Therefore, it is recommended to consult with a healthcare provider before using ashwagandha, especially if you have any underlying medical conditions or are taking any medications.
Potential Side Effects of Ashwagandha and How to Manage Them
Like any other supplement or medication, ashwagandha may cause some side effects in some people, especially in high doses or for long durations. The most common side effects of ashwagandha are:
- Gastrointestinal distress, such as nausea, vomiting, diarrhea, and abdominal pain.
- Headache, dizziness, and fatigue.
- Low blood pressure and heart palpitations.
- Insomnia and vivid dreams.
- Changes in blood sugar and thyroid hormones.
To minimize the risk of these side effects, it is recommended to start with a low dose of ashwagandha and gradually increase it as tolerated. It is also advisable to take it with meals to reduce gastrointestinal irritation and to avoid taking it before bedtime to prevent insomnia. In case of any severe or persistent side effects, it is advisable to consult a healthcare provider immediately.
It is important to note that ashwagandha may interact with certain medications, such as sedatives, thyroid hormone replacement therapy, and immunosuppressants. Therefore, it is crucial to inform your healthcare provider if you are taking any medications before starting ashwagandha. Additionally, pregnant and breastfeeding women should avoid ashwagandha, as its safety in these populations has not been established.
Who Should Avoid Taking Ashwagandha?
Apart from the precautions and contraindications mentioned above, there are certain groups of people who should avoid taking ashwagandha altogether, such as:
- Children and adolescents: Ashwagandha has not been studied extensively in these age groups, and its safety and efficacy are unclear.
- Pregnant and nursing women: Ashwagandha may stimulate uterine contractions and cause miscarriage or preterm labor in pregnant women, and may pass into breast milk and cause harm to the baby in nursing women.
- People taking certain medications: Ashwagandha may interact with medications that affect blood sugar, blood pressure, thyroid hormones, and sedatives, and cause adverse effects.
It is also important to note that individuals with autoimmune diseases, such as rheumatoid arthritis, lupus, or multiple sclerosis, should avoid taking ashwagandha as it may stimulate the immune system and worsen their condition. Additionally, individuals with a history of thyroid disorders should consult with their healthcare provider before taking ashwagandha, as it may affect thyroid hormone levels.
Safe Dosages of Ashwagandha for Different Age Groups
The safe and effective dosage of ashwagandha may vary depending on factors like age, sex, weight, and health status. However, some general guidelines are:
- Adults: 300-500 mg of ashwagandha extract or powder twice a day.
- Children and adolescents: 50-100 mg of ashwagandha extract or powder once a day, under the supervision of a healthcare provider.
It is important to note that pregnant and breastfeeding women should avoid using ashwagandha, as its effects on fetal development and lactation are not yet fully understood. Additionally, individuals with autoimmune diseases, thyroid disorders, or diabetes should consult with their healthcare provider before taking ashwagandha, as it may interact with certain medications or exacerbate underlying conditions.
Can Pregnant or Breastfeeding Women Take Ashwagandha?
Pregnant and breastfeeding women should avoid taking ashwagandha, as its safety and efficacy are unclear in these groups. There is a risk of adverse effects on the developing fetus or newborn, and it is advisable to consult a healthcare provider before using any supplements or medications during pregnancy or breastfeeding.
Studies have shown that ashwagandha may have potential benefits for reducing stress and anxiety, improving cognitive function, and boosting immunity. However, more research is needed to determine its safety and effectiveness in pregnant and breastfeeding women. It is important to prioritize the health and well-being of both the mother and the baby, and to discuss any potential risks or benefits with a healthcare provider before considering the use of ashwagandha during pregnancy or breastfeeding.
Interactions Between Ashwagandha and Other Medications
Ashwagandha may interact with certain medications and cause adverse effects or reduce their efficacy. Some of these medications are:

It is advisable to inform a healthcare provider before taking ashwagandha if you are taking any medications or have any medical conditions.
In addition to the above interactions, ashwagandha may also interact with certain supplements and herbs. For example, ashwagandha may increase the effects of supplements like GABA and valerian root, which can cause excessive sedation. It may also interact with herbs like St. John's Wort, which can affect serotonin levels and cause serotonin syndrome when combined with ashwagandha.
