What herbal medication helps eczema?

Herbal formulas don’t treat specific conditions, they are designed to treat the underlying pattern which is causing those symptoms. For eczema there are several patterns which may result in the specific manifestation of the eczema. Without knowing what particular pattern is causing the eczema in your kids it would be irresponsible to recommend a specific formula to you. That being said, herbal formula can be very helpful and so I would recommend seeing a local herbalist or acupuncturist so that you can get the most appropriate formula for your daughters.
