THC is only very slightly soluble in boiling water. Adding either some alcohol or some oil to the mix will help the THC dissolve. An ounce of whole milk or a half ounce of hard liquor to a cup of boiling water increases the tea's potency quite a bit. A drink, made with marijuana leaves, spices, butter and milk would dissolve even more of the THC.
Since THC doesn't dissolve in hot water alone and the material is later strained and never directly consumed, no strong effect will be produced from water-based herbal tea. Additional boiling time with added milk and honey may provide a suitable carrier for cannabinoids to dissolve into.
In order to get the thc transfer, you need saturated fat.If you're making tea because you enjoy the herb flavor,great. But if you're trying to catch a potent buzz, you'd be better off infusing the herb in milk-cream and adding it to your tea...
