We didn't start eating seasonings to make food taste good. We used them to keep us alive. Black pepper is a lung Healer and helps with pneumonia. We started eating it because if you ate it you lived. Now we eat it because it tastes good on chicken. Parsley is a kidney cleanser. We started eating it because if you at it you lived. Now we eat it because it tastes good on chicken. We lose the "why" of knowledge over time. Witches were the herbalists and medicine men of their villages. St John's wort is great for a lot of topical and internal issues so witches would grow it. Most herbs are forest dwellers so the herbalist loved in the forest. St John's wort also kills other plants and is toxic to sheep and cows. The farmer would teach his son "if you see the bright coming from the woods and killing the crops or sheep or cows its the witch woman". This meant he should tell the herbalist so they could come harvest and cull the st John's wort out of his land. Well he tells his son. And he tells his son. And the why is lost. Only the rote repetitive learning of "its the witch" remains. And then we burn them at the stake.
