Herbs vary in strength and potency from something as innocuous as ginger and garlic to something as powerful as Ephedra. Unlike synthesized medications,
herbs are quite gentle on the system. The over-the-counter psudo-ephedra cold medications are 15 times more potent than the herb. When used properly, the absence of side effects cannot be overstated. Because of their purity and gentleness the effects gained are prolonged and stable.
Oriental Medical Arts only uses TGA (formerly known as GMP) certified herbal products. Twenty-five years ago, Singapore, Australia, and Taiwan became suspicious of Chinese manufacturing standards. They set up an agency (TGA/GMP) to inspect Chinese herbal manufacturing plants. They also build their own factories in China. In order to import herbs into their countries, they must have the TGA stamp of approval
