The cross circulation test of spinal cord cat and dog head shows that its antihypertensive mechanism is mainly peripheral effect. The amorphous alkaloid Nn-9 from plumula Nelumbinis has a strong antihypertensive effect. Intravenous injection of 1-2 mg/kg for 2-3 hours in anesthetized cats can reduce the original blood pressure level by about 50%.

Xiangtan Village Sanlian is better than other lotus seeds in amino acids and protein 17, and is known as "the first lotus in China". At present, the mainstream processing method of Xianglian is mechanical processing (pure physical process processing), and the product produced is called Dilian.
