Both Jiaogulan and Ginseng are very similar in function. For example, out of the 82 Gypenosides of Jiaogulan, 4 of them are exactly the same as the Ginsenosides in Ginseng. Gypenosides number 3, 4, 8, and 12 are exactly the same as the Ginsenosides Rb1, Rb3, Rd and F2 respectively. A study at the Vanderbilt University in Germany demonstrated that Jiaogulan was 82% effectiveness in treating high blood pressure, while Ginseng only showed a 42% effectiveness in lowering high blood pressure. Jiaogulan differs from Ginseng in that most herbalists offer a caution to people with high blood pressure to avoid higher doses of Ginseng. Whereas with Jiaogulan there are no such restrictions.
