not sure if this is just a "me-thing" or what, but...
you don't need to put that many herbs there. you don't need to, i promise. especially if youre not following a formal ritual or guide from a formalized religion/spiritual space, because then you can just do whatever the fuck you want.
let me give you some advice, both metaphysical and mundane:
metaphysical: adding more herbs, depending on your beliefs may or may not make your spell/ritual work faster/have more oomph/etc., but that's not a guarantee, and regardless, if you have even the smallest itty bitty pinch of an herb with a corresponding strong intention, it will still work! do you think witches or practitioners or pagans of historical times would always have abundance or would use more than they needed/could afford/etc.? of course not! and their practice still thrived. yours can too.
mundane: adding more herbs can actually be harmful- especially when working with things like candles, rubs or anything that comes in contact/close to your body. for example, let's take a facial steam. so you're sick, right? congested and coughing, all that jazz. you take some water, boil it, and boil in some salt, add some eucalyptus, mint, and pine needle. then you go on and huddle over that bowl and breathe in deeply through your nose out your mouth. those herbs, the steam, the salt, should all help to break down the mucous in your lungs/sinuses and help you breathe better. but adding too many herbs will not only just waste your stock of (probably expensive- let's be real, getting good herbs is a hassle, particularly if you're going for good quality, organic and/or reputable) herbs and spices, it could also cause a negative effect of making your face/skin break out/causing reactions, etc. when putting herbs on candles, adding excess can and WILL increase the fire hazards- too many essential oils in your salve can cause allergic reactions as well. and in general it's just plain wasteful.
i see many people, especially on tiktok or who use tiktok a lot adding excess herbs and i just-
well i grew up using herbs in a mundane way so i know you don't need to add a lot of herbs unless you DO and most of the time with spiritual work you don't, but also i'm poor? i don't and never have had the money to spend on all the herbs to replace those i've used, and many of the spiritual herbs i use also double as kitchen spices, so i have to be frugal.
this was not well-written at all, and for that i apologize lmao, but long story short,
don't waste your herbs- you don't need to add all those herbs just to make it look "full" or "pretty". just use what's needed.
