Hazel wood for reflux??

My daughter has pretty bad reflux but her pediatrician doesn’t want to give her anything for it just yet as she is gaining weight well. She’s 15 weeks tomorrow. So I’m looking online and see that hazel wood is supposed to help with reflux, GERD, ulcers, etc. they have them in necklaces, I’ll post a pic of one I found below. We have the amber necklace and bracelet so I’m ok with her wearing stuff during the day.

My question is, has anyone heard of this? Have you used it and it worked or didn’t work for you or your LO?

Thanks to anyone who has any input!
