Effects on the circulatory system 1. Anticoagulant effect. 300% fungus decoction 1ml/100g gavage, 20d, experimental results show that fungus can extend the white clay part of thromboplastin time 12.06s, improve plasma antithrombin Ⅲ activity, has obvious anticoagulant effect. Black fungus polysaccharide 50mg/kg to mice static injection, intraperitoneal injection, gavage, there are obvious anticoagulant effect; in vitro experiments, black fungus polysaccharide also has a strong anticoagulant activity. 2. Anti-platelet aggregation. The aqueous phosphate buffer salt extract of black fungus significantly inhibited ADP-induced platelet aggregation in vitro and blocked the release of 5-hydroxytryptamine from ADP-activated platelets at a level lower than 16 μmol/L. The active ingredients of black fungus antiplatelet effect are water-soluble. It starts within 3h after 70g of black fungus is taken orally by human (borrowed from someone else's answer)
