Hi Vidya. The medicines or substitutes you give to your child are good for acute cases. If your daughter was my patient, I would rather insist you to go for herbals not only to give relief but to create natural resistance in the child against allergens. There are a lot of herbal combos available with Piper longum as the central medicinal herb which work wonderfully in children. Especially the combo of Piper longum, Cyperus rotundus, Aconitum heterophyllum, Pistacia integerrima have wonderful effect on children. It works on Asthma, cold, cough fever and protect child from recurring infections. It also promotes proper nutrients absorption and growth. It could be slow to act but harmless, non toxic and natural. Once it achieves proper duration of course, the effect sustains for much much longer times. It also has carminative and appetizing action on children. Our association of professionals arrange high quality, properly processed herbal combos for our own patients at concessional rates for HCM community. We strongly recommend to give this classic combo with honey to such children. Higher doses of this, however, cause gastritis. For any further information or query please feel free to contact through direct question on HCM platform. Hope it helps.
