Why You Should Tell Your Oncologist About Ayurvedic Medicines

"It's natural" does not mean "it cannot interact"

Ayurveda & Integrative

You may think:

"I don't need to tell my oncologist about my Ayurvedic medicine because it is natural."

It is important to tell them.

Herbs and other supplements contain active substances. These substances can sometimes affect medicines used to treat cancer.

They may alter how a medicine is absorbed, broken down or removed from the body. In some situations, this could reduce the effect of a cancer medicine or increase side effects. 

What should I tell my doctor?

Tell your cancer-care team about:

Ayurvedic tablets

Churna and powders

Kashayas and decoctions

Asava and arishta preparations

Herbal teas

Rasayana products

Vitamins

Mineral supplements

Protein or nutritional supplements

Over-the-counter herbal products

Any "immunity booster"

If possible, take the actual product, packaging or photograph of the label to your appointment.

Why is this especially important during chemotherapy?

Chemotherapy medicines are carefully selected and dosed.

Some supplements can affect the way medicines work in the body.

Therefore, a product that seems harmless may not be harmless when combined with a particular cancer medicine.

The same principle applies to radiotherapy, immunotherapy and targeted medicines.

What if my doctor says "No"?

Do not feel that you have to hide the medicine.

Ask:

"Can you explain why this may not be safe with my treatment?"

A good cancer-care team should be able to discuss your concerns respectfully.

What if my oncologist does not know enough about Ayurveda?

Give them the product details and, if possible, involve a qualified Ayurveda physician who is willing to communicate with the cancer-care team.

Remember

Never hide a medicine because you are afraid your doctor will disapprove.

The more your healthcare professionals know, the better they can protect you from avoidable interactions and complications.

This information is intended for education and supportive care. It does not replace consultation, diagnosis or treatment by a qualified healthcare professional. If you have cancer, do not stop, delay or change prescribed cancer treatment because of information found on this website. Tell your cancer-care team about all medicines, Ayurvedic preparations, herbs, vitamins and supplements you use. This is especially important for the Ayurveda section because interactions between cancer medicines and supplements/herbal products can occur.
