The side effects of Coronary Heart Pill have not been clearly recorded on the drug insert, if you feel obviously unwell after taking it, you should go to the hospital promptly. Coronary Heart Pill has the efficacy of activating blood circulation and removing blood stasis (promoting blood circulation and eliminating blood stasis in the body), regulating qi and relieving pain (relieving pain by unblocking qi). It is clinically used for the treatment of chest paralysis (chest tightness and pain) caused by qi stagnation and blood stasis (blood stagnation due to lack of circulation of qi) and cardiac stasis (heart veins and channels being blocked by stagnant blood), and for the relief of symptoms such as chest tightness and discomfort, shortness of breath and so on. The adverse reactions and contraindications of taking Coronary Heart Pill are not clear. Coronary heart pill needs to be used reasonably after identification by traditional Chinese medicine practitioners, and should not be taken on its own to avoid delaying the condition.
