Cordyceps has the effect of tonifying the kidney and benefiting the lungs, stopping bleeding and resolving phlegm; it can be decocted or incorporated into pills and bulk. Cordyceps is sweet in flavor and warm in nature; it belongs to kidney and lung meridians. It is used for treating tuberculosis cough, hemoptysis, chronic cough and asthma, night sweating (abnormal sweating after sleeping, stopping sweating after waking up), spontaneous sweating (involuntary sweating during the day, aggravated by sweating with slight movement), impotence, spermatorrhea, lumbar and knee pain, and post-disease weakness. Cordyceps should not be used by those who have superficial evil (evil in the muscle surface). Cordyceps Sinensis should not be used with sedative-hypnotic drugs, as it may increase the adverse effects of the drugs. If patients have any discomfort, please go to regular medical institutions; if you need to use Cordyceps sinensis, it must be used under the guidance of professional doctors.
