What is agarwood tea?
The leaves derive from leaves that grow on "the wood of God", Aquilaria Crassna, a legendary Eastern herb. Agarwood leaf beverage is not "tea", but "herbal infusion" because it is not Camellia Sinensis.
The delicate aroma with robust flavour makes it stand out from most of its brothers and sisters in the herbal infusion family.
How does it taste?
It is bitter when you take the first sip, followed by an intense lingering tangy after taste. You can feel it in your throat.
"Bitter hey?" so why should I bother steeping it?
Not everyone appreciates bitterness, but it is quite beneficial as "Saponin has the property of precipitating and coagulating red blood cells. Some of the characteristics of saponins include the formation of foams in aqueous solutions, hemolytic activity, cholesterol-binding properties and bitterness "( Sodipo, O. A., Akiniyi JA, Ogunbamosu J. U (2000)).

2) Better, deeper sleep: Terpenoids with sedative and anxiolytic effects found in agarwood leaves. It would relax your body and calm your mind (Mamoru Kakino, Gifu Pharmaceutical University).
