Kuding tea is cold, mainly for hypertension, hyperlipidemia and diabetes, similar to chrysanthemum. Chrysanthemum morifolium is also cold, both of them are cold. Just choose one of the two. Osmanthus fragrans tea has the effects of warming yang, whitening skin, removing toxins from the body, relieving cough, resolving phlegm, preserving health and moistening lung. It can be summarized as not catching a cold easily. Generally speaking, there is no harm to the body, but Kuding and Chrysanthemum morifolium can only choose one of them, or choose the "Chuju" with the least coldness and the highest medicinal properties. This is clearly recorded in Compendium of Materia Medica, and Chu Ju is the mildest of the four famous chrysanthemums. You can also take Chu Ju and Kuding. I hope my answer can help you.
