Toxicity is in the dose.
I can give you cookies with arsenic, eat one myself, have you eat one, have the taster eat one... we're all fine.
BUT.
If I make sure you eat 2 of them, every day?
🤮🤮🤒😵
Heck, as long as you have a small dose, you can have it in everything, including in candles!
It's useful like that.
Because, toxicity is in the dosage.
(It's a lot like religion in that way...)
