Hi, Thanks for writing in. Some medications like ashwagandha might help control cancer. However cancer should not be treated by this medicine alone and taking regular medical treatment is also advised. Ashwagandha is an ayurvedic preparation and has been in use for hundreds of years for its medicinal properties. Apart from suppressing certain cancer cells, it can also be used for conditions like arthritis, anxiety, trouble sleeping (insomnia), tumors, tuberculosis, asthma, a skin condition marked by white patchiness (leukoderma), bronchitis, backache, fibromyalgia, menstrual problems, hiccups, and chronic liver disease. Cancer can be due to many causes and all cancers cannot be cured with ashwagandha. You can purchase it from the retail store of well known ayurvedic medicine manufacturers in your place. Please take in recommended and discuss with your doctor if there are any potential side effects when taking chemotherapy treatment. Please do not worry.
