Hello, there is no incompatibility between these Chinese herbal medicines. They can be put together to make water and drink as tea. Among them, stevia can help relieve mental fatigue, promote metabolism, and is beneficial to health. Honeysuckle has the effect of clearing away heat and detoxifying, while lotus seed heart can remove heart fire, calm the heart and calm the mind. Since honeysuckle and lotus seeds are cold traditional Chinese medicines, they should not be taken for a long time, as this will cause the body's own balance to become imbalanced. It is recommended to drink it for a while and then take it for a while. If your body is hot, you can take it for a longer time. Hope my reply is helpful to you.
