Like any other supplement, Ashwagandha can have side effects. The common ones are mostly mild. However, some severe but rare reactions can occur. Learning about these effects will help you use them safely.

Severe but rare side effects of Ashwagandha

Although severe side effects are generally considered uncommon, they can occur. This encounter can particularly happen when Ashwagandha is consumed for a prolonged time or in high doses. Here is what one should watch for:   

  • Allergic reactions: Itching, swelling, or a skin rash can occur. Caution is advised for individuals with a sensitive immune system. Consult a doctor if difficulty in breathing is experienced.
  • Autoimmune triggers: Clinical reports suggest that Ashwagandha can stimulate the immune system. This indicates that this herb can worsen symptoms in people with autoimmune diseases, such as Lupus.
  • Liver injury: Rare cases of damage to the liver have been observed, with a few requiring immediate medical attention. Therefore, it is suggested to stop the use and consult a doctor first if symptoms like abdominal pain and/or Jaundice occur.
  • Imbalance of Thyroid hormone: Ashwagandha has proven activity in increasing levels of Thyroid hormone. This can worsen Thyroid conditions, if one has any. Consider monitoring the hormone levels under medical supervision. 

Who should avoid Ashwagandha

Ashwagandha offers numerous benefits for both men and women. Still, this natural remedy is not suitable for everyone. The groups given below should either consult a doctor before using it or altogether avoid it:

  • Pregnancy and breastfeeding: Several clinical reports have advised against using Ashwagandha during pregnancy and breastfeeding. Its safety profile is still unclear for these two phases.
  • Scheduled surgery: In case of any upcoming surgeries, stop taking Ashwagandha two weeks before. This is due to its known interaction with anesthesia.
  • Liver disease: As discussed before, liver injuries have been reported in some individuals using this herb. A doctor’s consultation is advised, or avoid using it if there are existing liver issues. 
  • Allergy: The findings of research published by Pharmaceutics in 2023 suggest that treatment with Ashwagandha is contraindicated for individuals with an allergy to the solanaceae family. 
Glossary:
Solanaceae is a plant family commonly known as the nightshade family. It includes many well-known species, such as bell peppers, potatoes, and tomatoes. Ashwagandha is also a member of this diverse plant family.

Drug interactions of Ashwagandha

Ashwagandha can interact with certain medications, potentially triggering side effects. So, always consult a healthcare provider if you are on any medication. Listed below are potential interactions:

  • Immunosuppressants: Ashwagandha can interact with and reduce the effectiveness of medicines prescribed for the immune system.
  • Blood pressure medications: Ashwagandha can increase the effects of these medicines by triggering a drop in blood pressure.
  • Sedatives: Taking sedatives in combination with anti-anxiety or sleeping pills can elevate the drowsiness effect.
  • Thyroid medications: As mentioned earlier, Ashwagandha can impact Thyroid hormone levels. In turn, this can significantly affect medication treatment. 
Warning:
Men with Prostate Cancer should be cautious with Ashwagandha use. Since it is known to increase testosterone levels, it can cause interference with hormone-sensitive Cancer treatments. A doctor’s consultation is strongly suggested.

How to minimize the side effects of Ashwagandha

If you are worried about side effects, here are simple tips to control or prevent them:

  • Purity of supplement: Be cautious while choosing Ashwagandha products. Consider reputable brands only, since some products may be contaminated and cause side effects.
  • Take with food: To prevent side effects such as nausea and stomach discomfort, take Ashwagandha with food or with milk/juice.
  • Dosage: Start with a low dose, typically 250-600 mg, and gradually increase if needed. Taking high amounts straight away results in increased side effects.
  • Monitor your body: Stop using it if unusual symptoms, like stomach pain or rash, appear, and seek professional advice.
  • Consult a doctor: Medical consultation is recommended for anyone experiencing a medical condition and taking medication to manage it. Timely intervention prevents unwanted effects.

Conclusion

Ashwagandha is a well-known herbal supplement known for its numerous health benefits. However, like any other health supplement, it comes with potential side effects and precautions. Common unwanted effects, such as drowsiness, mild headaches, or dry mouth, are generally temporary and manageable. However, severe effects, like allergic reactions or liver injury, are rare but should be addressed immediately.

Certain groups, including breastfeeding and pregnant women and people with autoimmune diseases or liver issues, should consult a doctor before use. Precaution is advised, as Ashwagandha can interact with various medications, like immunosuppressants. Start with a low dose and choose the correct brand for safe use. These considerations ensure that Ashwagandha can be incorporated safely and effectively into a wellness routine.
