bone loss is the result of an imbalance between the opposite bone resorption and bone formation. In the body, bone undergoes a constant turnover in which osteoclast cells remove its mineralized matrix whereas osteoblast cells deposit the new bone matrix. In the aging process, bone resorption becomes more dominant over bone formation and thus leads to bone loss. For example, estrogen has a function in inhibiting bone resorption and lack of estrogen (e. g., as a result of menopause) thus increases the loss of bone matrix.
In traditional Chinese medicine (TCM), bones are governed by the kidneys, a primary source of essence of life and of the Yin and Yang energy. Thus, a strong kidney function provides ample nutrients that promote a robust formation of bones. When the kidney function is weakened, bone loss outpaces bone formation and causes bone loss. Consequently, strengthening the kidney function is considered to be a main principle in TCM to address bone loss. Although it is to be interpreted by modern biomedical studies, Chinese herbal formulas that follow the principle have shown satisfactory results in stopping bone loss and increasing bone mass in clinical studies in China. BoneVigor is our signature formula that follows the principle for promoting bone health.
Bu Gu Zhi (Psoralea fruit) tonifies the kidneys, strengthens the Yang energy, reserves the essence. In studies of animal models, Psoralea extracts increase serum calcium levels and decrease urinary calcium excretion, reduce bone loss and lead to the gain in bone mineral density.1 A compound isolated from Psoralea is further found to inhibit the formation of osteoclasts, the cells that resorb the bone matrix;2
Gu Sui Bu (Drynaria) nourishes the kidneys and is well known among Chinese medicines for its property in promoting healing of bones after injury. In studies of osteoporosis animal models, Drynaria extracts can significantly increase bone mineral density and promotes bone-forming osteoblast differentiation and mineralization;3,4
Du Zhong (Eucommia) is a popular tonic for both the liver and the kidneys. The Chinese herb is well recognized for strengthening bones and tendons and is commonly used for lower back pain and joint pain. Extracts prepared from Eucommia have been shown to prevent bone loss from postmenopausal animals;5
Xu Duan (Dipsacus) is another Chinese herb that tonifies both the liver and the kidneys and strengthens the bones. Its extracts are also found to promote bone formation in experimental animals;
Tu Si Zi (Cuscuta seed) invigorates the kidneys and nourishes the liver and the bone marrow. Cuscuta seed extracts are shown to promote differentiation and mineralization of human osteoblast cells;6
Shu Di Huang (Rehmannia root) nourishes the Yin energy and tonifies the blood;
Bai Shao (White Paeony root) nourishes the blood, harmonizes the liver and relieves the pain;
Dan Shen (Salvia) promotes blood circulation and removes blood stasis. Blood stasis is often associated with osteoporosis in the pattern diagnosis of TCM. Indeed, Dan Shen extracts are able to prevent bone loss caused by ovary removal in animal models;7
