I went to the dermatologist twice with no remedies to cure my flat warts. All he did was prescribed Retrieve and aldara
cream which didn't work. I did many research online and didn't really find anything that worked. Tried Thuja cream but that's hopeless. In Sydney, there's no Thuja tablets because it's not available in retail stores. I don't think this is safe if it's not recommended to be sold in stores.
Anyways, I managed to go to my last resort, which was drink chinese herbal medicine.
