Overview Information

Indian cassia is a tree. It grows in parts of the Himalayas, other northern parts of India, Asia, and Australia. The leaf and bark are used as medicine.

Indian cassia is used for diabetes, cough, common cold, rheumatoid arthritis (RA), and many other conditions, but there is no good scientific evidence to support these uses.

In foods, Indian cassia is used as a spice or flavoring agent.

How does it work?

Indian cassia might help the pancreas release insulin. This might lower blood sugar in people with diabetes.


Uses & Effectiveness?

Insufficient Evidence for

  • Diabetes. Taking Indian cassia three times per day for 3 months might lower blood sugar in people with diabetes.
  • Asthma.
  • Bad breath.
  • Excessive crying in infants (colic).
  • Common cold.
  • Complications after childbirth.
  • Cough.
  • Diarrhea.
  • Gonorrhea.
  • Menstrual cramps (dysmenorrhea).
  • Heart disease.

  • Liver disease.
  • Nausea and vomiting.
  • Rheumatoid arthritis (RA).
  • Sexual problems that prevent satisfaction during sexual activity.
  • Skin damage caused by the sun.
  • Sore throat.

More evidence is needed to rate the effectiveness of Indian cassia for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: There isn't enough reliable information available to know if Indian cassia is safe or what the side effects might be.

When applied to the skin: There isn't enough reliable information available to know if Indian cassia is safe or what the side effects might be.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if Indian cassia is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Diabetes: Indian cassia might lower blood sugar. Watch for signs of low blood sugar and monitor your blood sugar carefully if you have diabetes and use Indian cassia.
