Many cartilage products are available on the market. Especially the undenatured UC-II form of collagen has proven to be effective in increasing flexibility of the joints, and alleviating joint discomfort in osteoarthritis as well rheumatic arthritis.
Collagen supplements also help in other autoimmune conditions.
Collagen is derived from animal sources.
Rudolf Steiner points out that remedies made from animal origin affect/strengthen the etheric body. In our time when the life forces are so stressed and more and more people suffer literally from devitalization of their life forces it is no wonder that these remedies are gaining in importance.
In the True Botanica supplement, also included is Stannum (tin) in potentized form. According to Rudolf Steiner this metal (in potentized form) helps the Ego organization to enter more deeply into the etheric body of the connective tissue and strengthen it.
