I really would not subscribe to this- "traditional" chinese medicine,in other words unconventional & unorthodox methods which have not been really tested & tried or subjected to the rigorous scrutiny of research & scientific testing/analysis; is definitely not the way to go.

There are many reasons why a woman could be having irregular periods- from medical conditions such as problems with the hormonal glands (pituitary,thyroid,adrenals & ovaries) to uterine problems to everyday things like anorexia,severe stress,weight gain/loss etc; so i would advise such a person to see their doctor in the first instance or a gynaecologist preferably.

There is no such thing as "abortion pill",at least not in naija anyway.There is a drug called Mifepristone (RU486) which is an abortifacient,but that is only used & prescribed by specialists in hospitals & under strict conditions & surveillance.

Of course,it is a different matter if your friend is actually intending to PREVENT pregnancy,in which case she can use the contraceptive pills, the "morning after" pill or the coil which are not abortifacients but rather reduce the chance of pregnancy occuring in the first place,after unprotected sex.
