IMO, alchemy effects should be revealed after some processings, not just by seeing results in potion. For example, alchemy tests, e.g. 4 recipes of different resources consuming. Each tests reveal only one of alchemy components properties by completelly destroying all ingredients and alchemical component.
Processing should explain their effects, e.g. herbal grind is still unknown effect.
Otherwise it will be used for 1 to 3 recipes in next world, by people who prepared some recipes against adder bite, and other hard to heal wounds like that.
