About Nature’s Sunshine KB-C TCM Concentrate
Traditional Chinese Medicine has guided herbal wellness practices for over two millennia, and KB-C TCM Concentrate represents the culmination of this ancient wisdom. Known in Chinese as “jian gu,” which translates to “strengthen the bones,” this concentrated formula brings together 18 traditional herbs specifically chosen to support your body’s structural and urinary systems according to Traditional Chinese Medicine principles.
In Traditional Chinese Medicine philosophy, KB-C TCM Concentrate is designed to strengthen the water element, which relates to the kidneys and bladder. The water element is believed to carry nourishment for the bones and regulate metabolism through the urinary system. This comprehensive approach addresses multiple aspects of wellness through a single, carefully balanced formula.
The Science Behind Traditional Wisdom
Nature’s Sunshine KB-C TCM Concentrate features a powerful 450mg proprietary blend that concentrates the benefits of multiple herbs into one convenient daily capsule. Each ingredient has been selected based on centuries of traditional use and documented benefits in Chinese herbal medicine.
Eucommia bark, one of the primary ingredients, comes from trees found high in the mountain regions of China. This herb has been used for centuries in the Far East, and Chinese herbalists believe it nourishes kidney yang while supporting ligaments and bones. The Chinese name “Du zhong” came from a Taoist monk who was allegedly immortal, reflecting the herb’s traditional association with longevity and vitality.
Achyranthes root brings its own unique properties to this formula. Growing naturally in China, Japan, India, and Nepal, this herb has a historical use that includes encouraging healthy urinary flow. Chinese herbalists believe achyranthes helps relieve the body of excess fluids while strengthening the liver, kidneys, bones, and tendons.
