Q: I want to enhance my immune system against colds and other infections. Which herbs will help?
A: Astragalus is perhaps the strongest herb for this and your first choice. However, taking astragalus as a single herb is not as effective as taking it in combination with certain other herbs like ginseng, which is how Chinese formulas are designed. Other herbs to consider which will which strengthen you against viruses (such as you find in colds and flus) are Andrographis, Olive Leaf Extract, Reishi and Maitake. If you are also suffering from some fungal infections, Oregano oil will be very beneficial and will work along with the other herbs.
