Yes, ginger in any form, (ginger beer, ginger tablets, even ginger biscuits), is good for stomach upsets, and arthritis.
And Vicks Vaporub....to clear a head cold, put a tablespoon of it in boiling water, put a towel over your head, and lean over the steam and breathe it in.....it will certainly clear out the sinuses.
Paw paw is another "cure all".....either by eating it for intestinal problems, or we also can get paw-paw ointment and it will fix cuts, bites, boils...anything.
