JADE WINDSCREEN Yu Ping Feng San Dietary Supplement
Kan Herb Company
Overview
This product contains a proprietary blend of Traditional Chinese Medicine (TCM) herbs, including Astragalus root, White atractylodes root, and Siler root, traditionally associated with immune support and 'wind dispelling'. While individual ingredients like Astragalus have emerging research supporting immune and general health benefits, the lack of specific dosages within the proprietary blend for each component makes it challenging to ascertain if they are present at clinically effective levels. The formula aligns with the classic TCM formula Yu Ping Feng San, which has some evidence for immune modulation and respiratory health, but the modern scientific validation for the synergistic effect of this exact blend and dosage as a dietary supplement is limited.
The Good
Based on a traditional Chinese medicine formula (Yu Ping Feng San) known for immune support.
Contains Astragalus, which has emerging research for immune modulation and broad health benefits.
Includes White Atractylodes and Siler root, traditionally used for addressing 'dampness' and 'wind' in TCM, which may translate to digestive and respiratory support.
The Bad
Proprietary blend makes exact ingredient dosages unclear, limiting efficacy assessment.
Most ingredients are best studied in combinations, not as isolated compounds.
Evidence for individual ingredients often comes from Traditional Chinese Medicine contexts, requiring more Western-style clinical trials for comprehensive validation.
Is it for you?
Best For: Individuals seeking traditional immune support, those interested in TCM formulas, people looking to strengthen their protective qi.
Skip If: You are pregnant, nursing, on medication, or have a chronic medical condition without consulting a healthcare professional.
