CommonCents That is interesting about derived sources .. as a potato is a source of Butyric acid , Indole is found in Green leaf Vegetables , And of course the AA is nothing other than Citric acid or Vitamin C ( Manipulated rose hips ..
They are also Vitamins ,
With the mints , I was using a ten year old piece of cedar wood that had broken down and washed so many times it would be difficult to test for anything except Tannic acid or Tannins ,
That makes the mint Bitter until it is over 8 or 9 inches tall ,
I like this conversation though ,
it gets interesting this way . learn things ,, I really enjoy ,,
