Anyway, I’ll assume you were being inquisitive rather than argumentative. You are incorrect. If you do a bit of research you will see why. However, if YW allows me to post this link, you can piggyback off this source:

Or, you can read Wikipedia (and check sources!!! so that you don’t end up like some people here who think that cancer can be cured with Tincturn).
