- Elderberry can be purchased in a variety of formats and contains quercetin. It’s also good for insulin/diabetes, which is interesting since the spike protein does seem to impact diabetics more severely. I like Rishi brand tea but you can also just pick it up at the grocery store as pills.
- Oregano essential oil (antibacterial, antiviral, antifungal – but use with care)
