Ba Ji Tian, also known as Morinda officinalis root, is a widely used herb in Traditional Chinese Medicine (TCM) valued for its ability to warm the kidneys, boost yang energy, strengthen bones and muscles, and relieve wind-dampness.
Its medicinal use dates back to the Shennong Bencao Jing (Shennong’s Classic of Materia Medica), where it was listed as a top-grade herb for treating conditions like impotence, weak bones, and organ deficiencies.
Ancient texts like the Mingyi Bielu noted its benefits for headaches, abdominal pain, and boosting essence, while the Yaoxing Lun emphasized its role in treating male sexual dysfunction and general weakness.
In the Ming Dynasty, Li Shizhen’s Compendium of Materia Medica described Ba Ji Tian as a moist, warming herb ideal for nourishing kidney yang, enhancing sexual function, and strengthening the musculoskeletal system.
