Traditional Chinese medicine composition for improving bone health and preparation and uses thereof

A method of preparing a traditional Chinese medicine composition for improving bone health, comprising:

• subjecting Eucommia ulmoides, Rhizoma Drynariae and Semen Cuscutae to extraction, concentration and drying to produce Eucommia ulmoides extract, Rhizoma Drynariae extract and Semen Cuscutae extract, respectively;
• and
• mixing the Eucommia ulmoides extract, the Rhizoma Drynariae extract and the Semen Cuscutae extract uniformly to produce the traditional Chinese medicine composition;
• wherein the method specifically comprises:
• (1) subjecting Eucommia ulmoides, Rhizoma Drynariae and Semen Cuscutae to extraction respectively with an ethanol solution under refluxing and filtration;
• subjecting a residue to extraction with a solvent and filtration;
• and combining filtrates to obtain a crude Eucommia ulmoides extract, a crude Rhizoma Drynariae extract and a crude Semen Cuscutae extract, respectively;
• (2) subjecting the crude Eucommia ulmoides extract, the crude Rhizoma Drynariae extract and the crude Semen Cuscutae extract to concentration;
• introducing maltodextrin to the concentrated Eucommia ulmoides extract and the concentrated Rhizoma Drynariae extract, respectively;
• wherein the maltodextrin introduced to the concentrated Eucommia ulmoides extract is 5% by weight of Eucommia ulmoides extract;
• the maltodextrin introduced to the concentrated Rhizoma Drynariae extract is 10% by weight of Rhizoma Drynariae extract;
• spray drying or vacuum drying and sieving to produce the Eucommia ulmoides extract, the Rhizoma Drynariae extract and the Semen Cuscutae extract;
• and
• (3) mixing the Eucommia ulmoides extract, the Rhizoma Drynariae extract and the Semen Cuscutae extract uniformly in a weight ratio of (60-80):(15-30):(5-10) to produce the traditional Chinese medicine composition.
