Are the benefits decreased or diminished when herbs are added to hot water to make a tea? I do it all the time but I have always wondered if anyone knows of a study done?
Depends on the herbs involved. Some could care less, others are significantly damaged. Have a look at the Herbal Medicine Making lesson on Infusions. We talk about it there. :0)
Don't use herbs or combine herbs with medications or use them during lactation or pregnancy without talking with your healthcare provider.
