i took a quick look at the sassafras tea idea, there seems to be alot of warnings with its consumption, and was illegal for a long time
Do not eat the small, white berries of the sassafras tree. Use any herbal ingredients with caution, as their toxicity may be unknown.
Sassafras is a blood-thinner (AKA: A Detoxification Agent for the Body) Use in small amounts. Make your blood too thin and it will come through the skin. Ask an old farmer and he'll tell you how much.
Sassafras contains agents that are known to cause liver damage and cancer according to FDA of the USA.
im not doubting that it may keep mozzies away, im just not sure im willing to lose my liver for the convenience
this information seems to be accurate, ive spent the last half hour reading different sites and articles on the subject, and all mentioned liver damage over time
