I am not a doctor and if i self administer wrong homeopathic remedy after reading symptoms online. will 2 drops three times a day for a month harm?, provided the wrong remedy is selected and i fail to match symptoms closely..no benefits.but any harm?

Nobody knows, but...: Truly homeopathic "medications" are made by repeated dilutions, so that the ingredient is not really in the medication anymore (just the "essence" of it remains). That means there is no active ingredient left to cause any benefit. However, that also implies that the homeopathic "medicine" should be pretty harmless. Other non-homeopathic ingredients are often added and may have scents and flavors.
