A: Whole World Botanicals has never had an adverse event report from people suffering from asthma who combine the Royal Desmodium supplement with their meds.
However, it is always prudent to let your doctor know what you are doing and to let him/her see the research literature on this product. People taking Royal Desmodium report feeling a great sense of relaxation, not just in their lungs, but in all of their muscles. This is very helpful in stressful situations when one tends to tighten up all over the body. This product does not cause drowsiness but because it is so relaxing some people take it before they go to bed.
