###Human: I am taking Kalarchikai for PCOS. Why are there abdominal cramps and thigh pain after taking it? ###Assistant: Hi. Kalarchikai is a well-known medicine to manage PCOD (polycystic ovarian diseases). It does not show any side effects when taken under a prescription of ayurvedic or Siddha physicians. You should take two to three grams twice a day after meals. The pain you have now can be a premenstrual pain. Wait for a few days and stop taking this choornam for a few days. After a week, you can start taking it in a recommended dose.
