Ledum Palustre is a homeopathic remedy made from the plant marsh Labrador tea that is often considered for achy, sometimes swollen joints, particularly when the pain begins in feet and travels upward. It is also commonly considered for those who are always cold, though cold applications make the achy joints feel better. Should also be considered for puncture wounds from sharp-pointed instruments, animal bites, and the stings of insects, especially mosquitoes.
