Eating raw ginger in foods or in teas generally doesn’t cause any known side effects or problems in healthy adults. As a medicine the quantity of ginger used will vary, for eg. to treat nausea or gas, adults can chew a one-quarter-ounce piece of fresh, raw ginger.

The impact and response for an increased intake depends on your body type, diet, climatic conditions and age. Idea is to be in moderation to avoid problems later.
