Classic yin and yang tonic formula for osteopenia: study protocol for a randomized controlled trial

Area of Science:

• Integrative Medicine
• Bone Health
• Traditional Chinese Medicine

Background:

• Osteoporosis and osteopenia pose significant global health challenges, primarily due to fractures.
• Current drug therapies for osteoporosis are costly and carry potential side effects.
• Natural herbal remedies present a promising alternative for managing bone density loss.

Purpose of the Study:

• To evaluate the efficacy and safety of the Classic Yin and Yang Tonic Formula in treating osteopenia.
• To determine the formula's impact on bone mineral density (BMD).
• To elucidate the underlying mechanisms of action for this Traditional Chinese Medicine (TCM) formula.

Main Methods:

• A multicenter, double-blind, randomized, placebo-controlled trial.
• Inclusion of participants aged 55-75 with osteopenia (T-score -1 to -2.5) and TCM-defined kidney deficiency.
• Assessment of BMD via dual-energy X-ray absorptiometry, alongside secondary outcomes including pain, quality of life, and biomarkers.

Main Results:

• The study is designed to measure changes in BMD as the primary outcome.
• Secondary outcome measures include pain intensity, quality of life, serum bone metabolism markers, and the neuro-endocrine-immune network.
• Safety and adverse effects will be rigorously monitored throughout the trial.

Conclusions:

• The Classic Yin and Yang Tonic Formula may offer a novel therapeutic strategy for osteoporosis if it effectively increases bone mass without adverse effects.
• Successful outcomes could partially elucidate the mechanisms of Chinese medical formulas in osteoporosis treatment.
• This research could pave the way for natural, effective treatments for bone density disorders.
