JHS material measure

Fine, thanks for the answer.
In terms of JHS, instead of me making JHS from one type of herb, is it effective in making JHS once using several herbs? For example oleander, shallots, chilies, I collect all of them in 1 container and then boil them to make JHS.
Effective I mean about its effect on pests.

Thank you in advance.

1. Yes.
2. When weighing is difficult In the case of raw herbs, JHS is often made by filling a container and filling it with water.
