Problems solved by technology

At present, there are ordinary compound Danshen tablets and capsules on the market, but the production technology of ordinary tablets and capsules is backward, the content of active ingredients is low, and there is no quality control index. It needs to be taken orally and absorbed through the gastrointestinal tract, and absorbed after the first-pass effect in the liver. Into the blood, low bioavailability, slow absorption. It is not suitable for the first aid needs of patients with angina pectoris
