How to convince a family member that homeopathic medicine is malarkey?

First off, here are some fun gifs. I like to pay it forward before making you read some stupid crap unlike some of these ingrates.






Okay, now on to my situation.
Staying with my gam gam (here's a pic you nasty mofos) as she's in her twilight years and needs someone to stay with her from time to time and just help her out and stuff. I do it occasionally and I'm happy to do it. Cook dinner with her and visit and it's fine.

Well one of the things I do when I stay here is help her with her medicine. No big deal. Old people take medicine and sometimes it's a lot and they can get confused.

Well tonight I get some instructions from a family member that's she's got some new medicine I need to give her. When I hear the names my cynic alarm goes off. Stuff that doesn't sound like real medicine. I ask if a doctor prescribed it. I am told yes. I ask which Doctor. I get told a name, but my bullshite meter is blaring at this point. She might as well have said Dr. Yogagirl.

I know this is long. Here's another gif.

bear with me.

So I ask her what she's a doctor of and finally get a straight answer. She's a "Doctor of homeopathy" at the "wellness center of Baton Rouge". (anyone know of this?)

I proceed to be way meaner than I should, pissing said family member off, calling it snake oil, quackery, crank meds, etc. Get bitched at and guilt tripped because "no it's not! It works! It helps!"

Whatever. Give my gam gam these stupid drops. Ask her (she used to be in the medical profession) if she thought it was quackery. She said yes. I asked if they helped. She said she didn't know. Looked at the invoice (oh it looks official all right. Doses and pseudoscience and all that jazz.) and it isn't cheap.

Is this worth fighting my family over? Hell, if they want I'll get some booze and some herbs and spices and make up a batch of Uncle Fr33's Miracle Tonic.

And they can pay me all the money they are wasting on this.

Is this a losing battle? Any tips to overcome the smooth talking salesmen that sold them on this? Anyone else have any experience with this stuff?

I appreciate any advice or guidance.

Sorry for all the words. Here's some boobs.
