Herbal supplements when prescribed by any doctor can be just as harmful as taking prescription medicines, so the point to be made and emphasized here would be to use them with proper guidance and not just because you assume certain supplements will work or because someone told you they work.

Remember many supplements are not regulated by the FDA like your medication , so you should only go ahead and buy them from a source which is proven to be high of very high quality and standards. If you are using herbs for medication purposes, make sure you have taken advise from your pharmacist or the doctor before doing so, since these medicines can have side effects you never thought of.

For depression, St. John’s Wort is known to be one among the many herbal supplements used, however, studies show that this is not to be taken when you suffer from bipolar conditions or sever cases of depression. If you consume this herb in a large dose at one shot, you may suffer from photo-sensitivity as well and hence pharmacists would say not more than 300mg on a daily basis, three times a day. So don’t do anything more than this or else you would be doing more harm than good. Follow the advice of your doctor and let them guide you the best way on using such supplements.

Another popular one amongst herbal supplements is Evening Primrose Oil , especially for those who suffer from PMS. PMS can happen when there is a low count of GAMMA LINOLENIC acid in the body and this herb can supplement the same. It would take around ninety days for the body to get its replenishing, however, be patient if you don’t see results right away, here we mean in two or three weeks. Sources say that not more than three grams on a day to day basis is needed by the body and later on two grams to maintain the levels of the acid within.
