Ginsenoside Rk1 is a minor ginsenoside, a type of dammarane triterpenoid saponin derived from the hydrolysis of major ginsenosides in Panax ginseng (ginseng) during heat processing. It is a specialty chemical widely recognized for its potential therapeutic applications in traditional and modern medicine.

It is commonly used for its anti-inflammatory properties, helping to reduce inflammation in various conditions. Additionally, it has been studied for its role in promoting cardiovascular health by improving blood circulation and reducing the risk of heart-related diseases. Ginsenoside Rk1 is also explored for its neuroprotective effects, potentially aiding in the prevention and treatment of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. Furthermore, it is utilized in skincare products due to its antioxidant properties, which help combat oxidative stress and slow down the aging process. Research also suggests its potential in enhancing immune function, anti-cancer activity by inhibiting tumor cell growth and inducing apoptosis, and supporting overall wellness.
