Tea made from Ginkgo biloba leaves has the effects of promoting blood circulation, removing blood stasis, dredging collaterals, relieving pain, astringing lung, relieving asthma, removing turbidity and reducing blood fat. For blood stasis blocking collaterals, chest pain, stroke, hemiplegia, lung deficiency, cough and asthma, hyperlipidemia, it is not as good as tea. I just pick up some by myself on the roadside and in the park, and few people buy them.
