Ginkgo biloba has the efficacy of activating blood circulation, removing blood stasis, clearing the channels and relieving pain, astringing the lungs (collecting lung qi) and calming asthma. Ginkgo biloba, that is, the dried leaves of the ginkgo tree, should generally be harvested in the fall when the leaves are still green, dried and processed for use. Ginkgo biloba is sweet, bitter, astringent, flat, and belongs to the lung and heart meridians, with the effect of activating blood circulation, removing blood stasis, clearing the channels and stopping pain, astringing the lungs and calming wheezing, resolving turbidity and lowering lipids (cleansing the body of impurities and reducing excess fat in the body). It can be used for the treatment of chest paralysis (chest tightness and pain) caused by blood stasis blocking the heart veins, stroke hemiplegia caused by blood stasis blocking the brain channels; shortness of breath and asthma caused by insufficiency of lung qi. It can also be used to treat hyperlipidemia. However, it should be noted that the use of ginkgo biloba should be avoided if there are problems such as dampness-heat and phlegm-dampness in the body. If you want to use Ginkgo biloba to treat and prevent diseases, it is recommended to use the medicine under the guidance of a traditional Chinese medicine practitioner.
