In Indonesia there is one herbal plant, actually this is a very poisonous plant species, when in contact with the sap it can cause the skin to become itchy and a rash to appear on the skin. This plant is called rodent tuber. Rodent taro has the scientific name Typhonium flagelliforme. Rodent taro leaves have long been used for cancer treatment, it needs special handling to process rat taro leaves into anti-cancer herbs. Even when using rat taro leaves for cancer treatment, sufferers will usually experience mild diarrhea for several days.So not all cancer patients can use the rodent tuber plant as a medicine, this is about whether or not an herb is suitable for treatment for some people. I remember a few years ago I had a friend who was suffering from breast cancer and he was successful with rat taro leaves to treat his cancer. He said that he soaked the rat taro leaves for up to 24 hours in clean water, then my friend mashed the rat taro leaves, after that he took the mashed rat taro leaf extract. I did not ask the dose that my friend used, because the most important thing was that he had recovered from his cancer. But there are also those who do not succeed in using rat taro to treat cancer.
Gosh that's amazing your friend recovered! There must be a lot of anti cancer plants we don't know about. I can see why it's a scary plant if it blisters the skin! In the UK there's a plant called giant hogweed which can do this if touched...(image via Google search)
