My apologies, I wasn't clear- I meant that this was a fluid meant for vaginal use during intercourse. Does that change anything? Is it easily made at home? Would you change anything?
I would still eliminate the oils due to their instability and the angelica since the problematic compounds can still be absorbed. The rest is not an issue unless you are also trying to get pregnant as the vitamin C acts as a spermicide.
As far as making something like that it wold be pretty easy. For any herbs you would have to use extracts so the fiber is removed. And I recommend using a hand blender to add the extracts slowly while the oil is being blended to prevent clumping of the extracts.
The vitamin E would only be added in a small amount to help slow oxidation of the oils, so this is fine.
