Well, as someone who suffered from ASTHMA as a child, and throughout my adult life, I found out at the age of 22 after experiencing a serious attack that certain medicines were contributing to the severity of them. The doctor told me after hearing my history with Asthma, that I was ALLERGIC to certain medications (aspirin & penicillin). So, I learned HOW to control my Asthma... holistically and I've been taking BLACK SEED OIL for 10 years now!! Works WONDERS for family and friends who also ATTEST to a FACT that it WORKS for WHATEVER 'AILS' us!! Asthma, diabetes, high blood pressure, eczema, to name a few health challenges and I HIGHLY recommend you TRY it!!!
