I have some issues with ingestion too. I have difficulty with most raw product.

I've found that making budder using washed herb, helps. after the budder solidifies and I remove it from the water, I bring it to a boil a second time with equal part water, and let it solidify again. this really helps wash out the solids.

I made some tinc and added some keif. made me sick. so I made the tinc into budder, which extracted all the good stuff, strained it, straining out the trich solids, and the budder was fine, made terrific medicated brownie bites with it, no stomach problem.
