Hi, I'm new to the list and I'm not sure if this is paleo or not but
Grapefruit seed extract has kept me healthy for almost a whole year. The
kids and hubby all get sick around me and I just pop those capsules and
nothing happens. They are a natural antifungal, antiviral and antibacterial.
They also contain zinc and vitamin c. I swear by them.
I used to get sinus infections all the time - now I'm down to only one a
year if I catch the flu. I buy the Solaray brand. They also sell the drops
in a little bottle (extremely bitter though).
