Suggestion: Hello, Polygonum multiflorum Thunb. There is a certain "toxin" in pharmacology, but Polygonum multiflorum Thunb. It also has the effect of "calming the nerves and invigorating qi". Be careful not to "stick or burn" during processing, otherwise it will be toxic. Eating tonic is a good thing, but pay attention!
A toast to your health.
