Yes, but not overnight. Most asthmatics tend to be highly allergic. Only as the immune system strengthens under homeopathic treatment will the allergic tendency reduce and the asthma improve. It can take a long time especially in adults who often are on multiple inhalers and other medicines. These drugs make it difficult to discern clearly the patient’s symptoms since the drugs do a good job of suppressing the asthma. Both acute and chronic homeopathic medicines may be employed in the treatment of asthma.
