 Pine gum (Pinus sp). Pine gum is traditionally used to treat sprain or tendonitis-like pain. To our knowledge, however, no scientific research has been conducted on pine gum.

 White willow (Salix alba). The bark of the white willow contains salicin, the molecule that is at the origin of acetylsalicylic acid (Aspirin®). It has analgesic and anti-inflammatory properties. Although it has been used for thousands of years to treat tendon conditions, no clinical trials have been conducted to confirm this use.
