Thread: Does Calea zacatechichi "expire"

I've never tried it myself, but most herbs, pills, medications, etc tend to lose potency after such a long time. It does vary a lot depending on the substance though, and since you kept it in your drawer (away from sunlight), it might still get the job done.

I say try it out and decide for yourself. Then post back in case anyone else needs to know.

I use a lot of herbs and they do often lose potency. I had some tablets which were excellent, but stopped using them because of a few side effects (affected performance at work) but then took them again on holiday, and found they had lost a lot of potency.

It should work and if the herb is calea it should be dried in the sun, abit mosit stuff damages the herb once dried
