The manifestation of this syndrome includes oligomenorrhoea, amenorrhoea, anovulation, numerous anteral follicles, hyperandrogenemia and hirsutism.

                                                                                                                                           a)Oligomenorrhoea/ Anovulation 

                                                                                                                                           b) Clinical or biochemical signs of Hypernadrogenism.

In unani system of medicine, the disease has not been mentioned under the term pcos but its translation has been done in arabic as :"Marz e Ikhyase Khusyaturrahem". This disease has been described by unani physician under the heading of amenorrhoea, obesity, phlegmatic disease and liver disorder. Unani concept of PCOS is mainly based on only dominance of Khilte Balgam (phlegm). One of the abnormal form of balgam is balgam e mayi which is thinner in consistency and can accumulate in the sacs to form cyst. A review of unani literature shows that Fue Mizaj e Barid leads to the combination of sign and symptoms like  menstrual abnormalities, oligomenorrhea, amenorrhoea, hirsutism, obesity, acne, hoarseness of voice and uqr (infertility) which are sugggestive of PCOS. Due to the unavailability of safe and effective drugs, scientific evaluation of unani drugs is quiet necessary. Therefore darchini (Cinnamomum Zeylanicum-arranged from sri lanka) is selected to study their efficacy in PCOS.The present design will be single blind, standard control and randomized study and place of study will be Ajmal Khan Tibbiya College and Hospital with a sample size of 30 patients in each group. The data will be analyzed by using appropriate statistical tools and will be presented in the form of tables and graphs.
