Saffron: either a few strands in hot water as a tea, or the much more affordable saffron extract tablets; gives a mildly speedy/stimulant effect, genuinely interesting.
Valerian root extract: smells like feet, knocks you off of your feet.
Licorice root: sugar free sweetener that increases your BP in larger amounts, I literally use a stick of it to stir my tea, the sweetness is felt at the back of the mouth and typically comes on as an aftertaste, doesn't have a strong anise flavour.
Kanna: a small plant from South Africa that an extract of will give entactogen effects (reminiscent of MDMA, but with a much lower ceiling)
Syrian Rue Seeds: seeds which contain harmala alkaloids, the thing that changes DMT into a 3-hour experience in Ayahuasca. The seeds are traditionally used as an incense in Persian/middle eastern cultures.
Ginger: it has 3 different properties if left fresh, dried or cooked. The main spicy component of fresh ginger becomes more pungent if left to dehydrate (dried ginger), or becomes sweeter if cooked/baked from fresh (the molecule literally ends up closer to vanillin, the main flavour of vanilla)
Nutmeg: consumed in a large quantity raw, will causes stoning and mild anticholinergic effects.
Cloves and clove oil will block out a tooth ache.
Poppy seeds have a very small amount of morphine naturally on them, you can make a painkilling tea from them, but I wouldn't recommend doing this, and would suggest if ever attempted to titrate up slowly.
