Silk protein
Synopsis of Silk protein
History
Silk protein, derived primarily from the cocoon of the Bombyx mori silkworm, has a long and respected history in traditional medicine, especially in East Asian cultures. For centuries, practitioners of Traditional Chinese Medicine (TCM) have utilized silk protein and its derivatives—such as sericin and fibroin—not only as a nourishing food source but also as a remedy for various ailments. Ancient texts cite its use in promoting general health, supporting skin regeneration, and enhancing wound healing. Silk powder was sometimes included in topical preparations for treating burns, ulcers, and skin irritations, believed to accelerate recovery and reduce scarring thanks to its unique amino acid composition.
In addition to topical applications, silk protein has been consumed orally as a tonic, valued for its high-quality protein content and bioactive peptides. It was often recommended to support vitality, strengthen the immune system, and improve complexion. Silk protein's mild nature made it suitable for use in convalescent diets and as a restorative supplement.
Herbalists have also combined silk protein with other botanicals to enhance their synergistic effects. For example, it is sometimes blended with ginseng or goji berry to further boost energy and resilience, or paired with pearl powder for skin and beauty remedies. Its compatibility with a wide range of herbs and its gentle profile make it a cherished component in traditional and modern herbal formulas alike. Today, silk protein continues to gain recognition for its nutritional and therapeutic benefits, exemplifying its enduring value in natural health and wellness traditions.
Traditional and scientific validation
Silk protein, derived primarily from the cocoons of the Bombyx mori silkworm, has a long-standing history in traditional Asian medicine and nutrition. Historically, silk and its derivatives were consumed in various forms for their purported health benefits, including enhancing skin and hair health, and supporting general vitality. In recent decades, scientific interest in silk protein, particularly its main components—fibroin and sericin—has grown due to their unique amino acid profiles and bioactive properties.
Several laboratory and animal studies have indicated that silk protein may offer antioxidant, anti-inflammatory, and immune-modulating effects. For example, research has demonstrated that silk protein hydrolysates can improve lipid metabolism, support liver health, and promote wound healing. Preliminary human studies have explored silk protein supplementation in functional foods, with some reporting improved skin hydration and elasticity, as well as potential benefits for muscle recovery and satiety due to its high glycine and alanine content.
Despite these promising findings, comprehensive clinical trials in humans remain limited. Most existing studies are small-scale or preclinical, and further research is needed to fully validate the nutritional benefits and safety of silk protein supplementation. Nonetheless, its excellent digestibility, hypoallergenic nature, and the presence of bioactive peptides suggest that silk protein is a promising ingredient for future nutritional applications. As scientific understanding grows, silk protein may gain an increasingly important role in health-promoting functional foods and dietary supplements.
