Poria cocos is a traditional Chinese medicine, which can soothe the nerves. For example, some patients with insomnia and forgetfulness can effectively alleviate the symptoms of insomnia and forgetfulness by drinking some water soaked in Poria every day. However, it should be noted that taking10g a day is enough, but the effect of soaking in water is not as good as that of decocting. You can directly put10g of Poria cocos in the pot, and then add 6 bowls of water until only one bowl remains.
