In your opinion, what are the best herbs, supplements, or herbal remedies that will increase the appetite.

Any tips will be appreciated.

Thanks in advance.

Those are all psychological in impact at best... purely a placebo effect.

I think ginger can help you with increasing appetite because it deals with indigestion and stimulates the appetite. You can cut a raw ginger into smaller slices and boil with hot water to make a tea. You can add milk and sugar to make the taste and try to drink a few times daily.
