Siberian Ginseng, otherwise known as Eleutherococcus Senticosus, is indigenous to China and has been used for centuries in traditional medicine to enhance mental focus. Clinically, Siberian ginseng has been studied for its potential benefits to the brain. Studies have shown that the herb may be beneficial in improving mental clarity and cognition, enhancing memory and learning skills, and reducing stress and fatigue levels. It is believed that these effects are due to the herb’s antioxidant properties, which help to protect the brain from free radical damage and promote healthy nerve cells.

• A study from 2017 published in the journal Food & Nutrition Research suggests that Siberian ginseng may help to improve mental clarity and cognitive performance in adults between the ages of 50 and 70. The study found that participants taking 2 grams of Siberian ginseng for 8 weeks experienced a significant improvement in short-term memory, logical thinking, and executive functioning.

• A study from the Journal of Ethnopharmacology suggests that Siberian ginseng may help reduce stress, anxiety and fatigue in adults. The study found that daily consumption of 800 mg of Siberian ginseng extract helped to improve overall wellbeing and reduced symptoms related to anxiety and depression.

• In a study published in the journal Pharmacognosy Magazine, scientists found that Siberian ginseng had powerful adaptogenic properties. This means it can help the body to adapt to stress more easily and can improve overall mental clarity and focus.

• A 2018 study published in Phytomedicine looked at the effects of Siberian ginseng on physical performance. The study found that daily supplementation of 500 mg of Siberian ginseng for 8 weeks significantly improved muscular strength, endurance and exercise capacity in healthy adults.

• Finally, a 2020 study published in the journal Herbal Medicine suggests that Siberian ginseng may be beneficial for treating symptoms related to clinical depression. The study found that daily supplementation with 1200 mg of Siberian ginseng extract significantly reduced symptoms related to depression and improved overall cognitive performance.

Overall, these 5 studies suggest that Siberian Ginseng may have beneficial effects on mental clarity, cognitive performance, physical strength and endurance, stress reduction, anxiety relief and clinical depression.
