Review: Good quality. - Helps with allergies and inflammation. Being using this for years.
Review: Use this if you get red patches - My chiropractor told me I must have high histamine because anytime I get hyped up I have red patches on my throat and chest, the quality is great, very effective and the value for the money is amazing. I don’t know if this is helping with pain also but I can say I’ve had to take less ibuprofen

### ⭐⭐⭐⭐⭐ Good product. Buying from Amazon, not so good.
*by D***A on January 6, 2026*

As a Prime member the product should have arrived on time, not two days late. Good product but delivery leaves nothing to be desired. It wasn’t due to USPS. Seems to be more of a carrier problem which is not USPS.
