Well, its good to hear that you are in otherwise good health. The PCO is probably what we would call a stagnation of blood or phlegm. Depending on which one, we would seek to basically just remove it so that your reproductive functions could work better. Acupuncture is often used in conjunction with herbs for this specific issue. The acupuncture stimulates the circulation of Qi energy in the local area as well as addressing the deeper emotional issues that may have created the problem in the first place.
Herbs do much the same thing, but from the inside out.
They are both very good for this, especially used together. Herbs vary in cost. Those herbs will come in raw form, meaning lots of roots and twigs that you cook at home and then drink three times per day. Those are easier to take as they come in pills or capsules, but they can't be modified for the individual which is an important component of Chinese herbalism. Finally there are those who write herbal prescriptions that are individually modified and yet come in the capsules.
