Hi Larissa, Sometimes i feel the same as your family.
I have a couple of receipes. The first has (for me) too many hard to find ingredients but the second is better.

1- Arthritis poultice - 6 parts mullen leaves - 9 parts slippery elm bark - 3 parts lobelia - 1 part cayenne

add 3 oz. mixture to boiling hot water to make a paste. Spread the paste on a cloth and apply to affected parts.

2- Arthritis Liniment - Wintergreen - yerba santa

Mix in equal parts. Put any amount of mixture in enough olive oil to cover. Simmer for 30 minutes. Strain and apply to affected parts when cool.
