Look for Harmine HCl or freebase. It's fully legal in most of the world and with a bit of searching can be found in multiple places. You could do an extraction as well, but the stuff isn't that expensive.

IMO, plant sources are great as just that... sources. I have a lot of experience hit and miss and weak drugs from consuming plants. It leaves me frustrated and wanting most of the time. You just can't be sure how much of what is in your plants until extracted. Whenever possible, I will either extract the goods or buy pure chemicals.

If you want to suck on chlorophyll and tannins, be my guest.
