Among them, ginsenosides are considered to be the main medicinal components. There are more than 40 kinds of ginsenosides that have been confirmed, among which saponin Rh2 has the strongest activity. Scientific studies have confirmed that ginsenoside Rh2 can effectively regulate human immunity and inhibit tumor cell proliferation. Ginsenoside Rh2 is a natural small molecule with lipophilic nature, which can easily cross the blood-brain barrier and is highly effective and non-toxic, without side effects, and can be taken for a long time. Therefore, it is suitable for use before and after surgery or during radiotherapy and chemotherapy, which can effectively protect immune organs, enhance immune function, facilitate the normal functioning of immune surveillance and clearance, prevent cancer recurrence and metastasis, and is suitable for tumor patients and other critically ill patients and the elderly and frail people. Because of this, ginsenoside Rh2 can play an important role in the recovery process of cholangiocarcinoma patients. Currently, ginsenoside Rh2 used in clinical practice is in high demand and therefore requires patented technology for industrial extraction, and only through patented technology can we ensure that the content of finished ginsenoside Rh2 products meets the optimal absorption rate of 16%.
