Turmeric is a herb that is- actually lemme skip the herb-o-babble part and to the powder part.
Turmeric powder, to name a few uses, is a cuisine spice, a dye powder, but most importantly a healing herb - when used properly. Boil some plain water and pour into a cup, and then pour in a dab of powder. Wait for it to settle, then carefully drink the resulting water.
