Erethema is controlled by antihistamines, corticosteroids, cold water treatment etc. It may correct within six weeks but may return. I would recommend you to give her turmeric powder + Sugarcandy powder + Neem (margosa) powder in 1:1:1 ratio about 1/4 of tsp and mix in honey and let her lick. Do it twice or thrice for at least two weeks. If anything of these three powders is missing, give other two to start with. If you can find Giloy satv give it too about 125 mg twice. It s precipitate of Tinospora cordifolia. Alternatively Guduchi capsules of Himalya herbals gave the same. You may cut the capsule and pour content in a bowl, mix in honey and other three hebs- sugarcandy combo said above and give to child. No need to discontinue present medicine. There is no interaction of these Ayurvedic Medicines and allopathic medicines. Absolutely safe. There will be no need to go to ER if rashes start subsiding. In that case Ayurvedic Medicine may be contained beyond four to six months and may withdraw or reduce allopathic medicine as per your doctor s advise. If it is controlled by these herbs, it will not return easily provided full treatment is taken. Hope it helps. For any other query, pl feel free to contact me through direct question. Note: medicine may be found through Net. In India its commonly available. For turmeric also a capsule viz. Haridra has the same content and cut and poured like Guduchi.
