Um, I think there might be some confusion here. Leishmania is a parasite transmitted by sandflies, that causes huge ulcers and possible multiple organ infestation. The ecto (skin) parasite that is associated with rosacea is demodex. If you google "medical study rosacea demodex" you will see this is proven by certain studies to be causative for rosacea. Demodex is a far less dangerous skin parasite. I am using the cloves, wormwood and black walnut tincture for demodex too thought -- and I think it's helping! Thank you :)
