I extracted 2 grams of dried salvia leaf with warm acetone and 90% IPA. I explain the reason for using warm acetone here.
Instead of infusing the extract onto dry leaf, I deposited it onto 5 grams of corn starch. I explain the reason for avoiding leaf, and using a non-porous substrate here and here.
For comparison, I have attached pictures of the cross section of a typical dried leaf, and corn starch granules in a broken grain of maize. The dried leaf looks like a sponge, the starch granules are smooth and non-porous.
