Seed therapy is a complementary healing method, often linked to Sujok therapy, that uses the life energy in natural seeds (like mustard, beans, or peppercorns) applied to specific body points (acupressure/correspondence points on hands/feet) to relieve ailments, based on principles of "like cures like" and energy balance, where seeds may change appearance as they absorb negative energy. There's also seed cycling (eating specific seeds at different cycle phases for hormonal balance) and seed treatment for plants (protecting crops).
