This medicine is indicated in various skin problems including ringworm. You can take it thrice in a day but first get it prepared with globules in some homoeopathic store. 4-5 globules in one dose. It can take one month to six months to get cure but if this medicine does not work then consult homoeopathic physician for the appropriate medicine.
1000 is a very high dosage. You can take Pancreatinum 30CH, 2-3 drops in a tsp of water thrice a day. Depending on your symptoms, you might be needing more medicines. Pancreatinum alone might not be sufficient or indicated. I suggest you consult a good homoeopathic doctor near you before starting the medication. Hope this helps.
Maintain half an hour gap between food/drink/any other medicines and homeopathic medicine.
Avoid any strong smell in the mouth while taking medicine e.g. camphor, garlic, onion, coffee, hing
