Written by Greg Arnold, DC, CSCS. Participating healthy male runners found that a combination of panax ginseng and danshen, taken daily for 7 days prior to downhill running, significantly improved their muscle damage and arterial stiffness and significantly increased their range of motion as well, compared to the runners in the control group.

botanicals - GinsengPanax ginseng is one of the most popular Chinese herbs, dating back thousands of years 1. The major components of ginseng, ginsenosides, are thought to protect blood vessels by scavenging free radicals 2 and increasing nitric oxide production 3. Another Chinese herb, danshen, has also been shown to improve circulation 4 and scavenge free radicals 5. Because of these health-promoting properties, Panax ginseng and danshen are often mixed in herb formulas in Chinese medicine in the hope they act together (“synergistically”) to promote health 6.

Research now suggests that panax ginseng and danshen together may improve muscle recovery after exercise. A 2016 double-blind, placebo-controlled study 7 involved 23 healthy males aged 21 to 31. They received either 1.75 grams of panax ginseng with 1.75 grams of danshen per day (12 subjects) or a placebo (11 subjects) for 7 days. On day 8, each subject performed a downhill running test. The test consisted of a 5-minute warm-up on the treadmill after which each subject walked or ran while the treadmill slope was increased 1 % every minute until the subjects could not continue the test. The subjects were then followed for the next 72 hours.

The researchers noted three significant changes between the two groups:

After 72 hours, those in the ginseng group experienced a 6% significantly greater range of motion of their thigh muscle compared to placebo (105 versus 99 degrees, p < 0.05), indicating less muscle damage from the downhill running.

After 48 hours, those in the ginseng group had a significantly lower increase in creatine kinase levels (190 versus 350% increase, p < 0.05), a marker of decreased muscle damage 8.

After 24 hours, those in the placebo group had a 12.9% higher rate of arterial stiffness (called “carotid-femoral pulse wave velocity” 9 compared to the ginseng group (503 versus 577 centimeters/second, p < 0.05), another marker of increased muscle damage 10.

For the researchers, “A short-term Chinese herb supplementation incorporating panax ginseng and danshen was effective in ameliorating the delayed onset vascular stiffening induced by acute eccentric exercise, possibly via the reductions in oxidative stress and systemic inflammation.”
