About Nature’s Sunshine HY-C (Chinese)
Traditional Chinese Medicine has guided wellness practices for thousands of years, recognizing the importance of balance within the body’s natural systems. Nature’s Sunshine HY-C (Chinese) brings together 16 carefully selected herbs that have been valued in Eastern traditions for their ability to support the body’s natural processes and promote overall well-being.
This thoughtfully crafted formula represents what Traditional Chinese Medicine calls “bu yin,” which translates to “supplement yin.” In Chinese wellness philosophy, yin represents the cooling, moistening, and nourishing aspects of the body. When these qualities are in balance, the body can better maintain its natural harmony and support healthy metabolic processes.
Traditional Eastern Wisdom Meets Modern Quality
The herbs in HY-C (Chinese) work together to support what Traditional Chinese Medicine describes as “reducing fire and strengthening water” in the body. This ancient concept refers to supporting the body’s natural cooling and moistening processes while helping maintain balance in the glandular and circulatory systems.
Each 930mg proprietary blend combines roots, bark, rhizomes, and other plant parts that have been treasured in Chinese herbalism for generations. The formula includes primary herbs like eucommia bark, traditionally valued for supporting liver and kidney function, and rehmannia root tuber, which has been used to help maintain healthy blood sugar levels already within normal range.
Key Traditional Herbs
Ingredient | Botanical Name | Traditional Use |
---|---|---|
Eucommia Bark | Eucommia ulmoides | Liver, kidney, and muscle support |
Glehnia Root | Glehnia littoralis | Respiratory and lung support |
Rehmannia Root Tuber | Rehmannia glutinosa | Blood sugar support, kidney nourishment |
Ophiopogon Root Tuber | Ophiopogon japonicus | Lung function, moisture support |
Kudzu Root | Pueraria lobata | Circulation and muscle relaxation |
HY-C vs. HY-C TCM: Understanding the Difference
Nature’s Sunshine offers two versions of this traditional formula to meet different preferences and needs. HY-C (Chinese) provides the complete traditional formula in its original proportions, delivering 930mg of the full herbal blend per serving. This version offers the complete spectrum of herbs as they have been traditionally combined for centuries.
The HY-C TCM Concentrate, by contrast, provides the same herbal combination in a more concentrated extract form, requiring only one capsule daily versus two capsules of the traditional HY-C formula. Both formulations provide the benefits of this time-tested herbal combination, with the choice depending on your preference for traditional preparation versus concentrated convenience.
Supporting Your Body’s Natural Balance
The herbs in this formula work synergistically to support various body systems. Ophiopogon is traditionally used as a lung moisturizer, supporting respiratory comfort and yin qualities. Trichosanthes root has been valued for its cooling properties, while achyranthes root supports the body’s natural fluid balance and structural health.
This thoughtful combination of complementary herbs reflects thousands of years of Traditional Chinese Medicine wisdom, bringing ancient knowledge together with modern quality standards to support your wellness journey naturally.
Recommended Usage
Take 2 VegCaps with a meal three times daily. For best results, use consistently as part of a balanced lifestyle that includes proper nutrition and regular exercise.
