Is It Safe To Have Siddha Medicines For PCOS?

Hi i have PCOS for some 3 yrs. I took metformin for 6 months, after that Krimson 35 hormone tablet for 3 cycles, but my periods didnt get regular. Now it didnt come for 6 months, so i moved to siddha medicines. siddha doctor asked me to take abdomen scan and come next week also he prescribed some medicines include mensoon. My previous scan reports revealed that i had only few small sized cysts. Now is it a good option for me to try siddha?? pls advice.
