Hi, you should try to avoid caffeinated beverages, alcohol, beef, onions, and hot species. Seafood are not recommended. Curries, turmeric, coriander, chilli, cumin, fennel, pepper, and mustard are not recommended, because they are irritating and may hinder the progress of improvement. And when you are taking the pill, you cannot take other herbal medicines at the same time, but chemical medicines are allowed.
