Asthma in children may be caused by reflux [gastro-oesophagal reflux] In these cases, Asa foetida D30 [suck twice a day a globule] can be very useful. This often happens after an induced birth! The baby may also have mastitis. In ureter reflux, I have personally treated children with Asa foetida that has prevented a complicated operation. This wonderful tip I learned from the French homoeopath D. Grandgeorge, and I am extremely thankful that he shared his experience and saved so many children!!
