Epiphyllum is a helpful herb in Chinese Medicine. It works to cool off hot feelings in your lungs and helps you stop coughing. It also helps you clear out sticky stuff in your throat called phlegm.
This herb is not just good for your lungs, but it also helps when your stomach or heart feels off. Some people find it helps when they have blood in their throw-up. It's often used for people who have lung issues, like when it's really hard to breathe well.
Remember, it's always good to talk to a knowledgeable person before starting new herbs or foods for your health.
