Lianzixin tea is a tea made from lotus seeds. The fruit after the lotus withers, the lotus pod, contains the lotus pod kernel. After removing the dark brown shell on the surface of the lotus pod kernel, the lotus pod kernel is obtained. The lotus kernels (lotus seeds, lotus seeds) in supermarkets usually do not have the green bud-shaped heart. Because the lotus seed heart has higher medicinal value, it is removed and processed into other products and sold separately. Lotus seed heart has the effect of clearing away heat and removing internal heat. It can soothe the mind and relieve insomnia symptoms caused by irritability. Its side effects are relatively small, but it tastes bitter and is slightly cold. Taking too much may cause gastrointestinal discomfort depending on the individual's constitution. In addition, Lotus Seed Heart astringes liquid to stop sweating and has a certain astringent effect, so patients with constipation caused by slow conduction in the large intestine should not take it. Generally speaking, just put seven or eight pills in to make tea. Of course, everyone's situation is different, and you can adjust it appropriately.
