Can Portulaca oleracea treat white hair?

Portulaca oleracea does not have a definite effect in treating gray hair. As a commonly used traditional Chinese herb, Portulaca oleracea has functions such as clearing heat and detoxifying, cooling blood to stop dysentery, and relieving dampness and reducing swelling. It also offers certain benefits to skin and hair health, such as enhancing scalp blood circulation and promoting nutrient supply to hair follicles, which may indirectly help prevent or slow down graying, but it does not have a direct therapeutic effect. The herb's ability to clear heat and cool blood might provide some auxiliary improvement for cases of gray hair caused by blood heat, but this does not mean it can be used as a specific drug for treating gray hair.

Hair color is determined by melanocytes within the hair follicles. When melanocytes cannot produce sufficient melanin to transfer into the hair shaft, gray hair appears. The formation of gray hair is mainly related to multiple factors such as heredity, age, stress, and nutritional status, for example, declining function of melanocytes. Therefore, the effect of treating gray hair solely through consuming or applying Portulaca oleracea externally is limited. Although Portulaca oleracea contains some nutrients beneficial to hair health, the effectiveness of these components in treating gray hair remains unclear.

Therefore, when dealing with gray hair, one should not rely solely on Portulaca oleracea for treatment. It is advisable to seek timely medical consultation and maintain good living and dietary habits.
