Proven Health Benefits
Improves Memory and Prevents Brain Disorders
A convincing number of studies suggest that Rg3 can improve memory and prevent brain disorders through its neuroprotective effects:
- In mice, oral administration of Rg3 for 4 days significantly reversed memory impairment induced by ethanol. 
- In cultured rat brain cells, Rg3 protected against glutamate-induced neurodegeneration. 
- A cell study reported that pretreatment of brain cells with Rg3 resulted in increased survival rate via its antioxidant and anti-inflammatory properties. 
- In an animal model of brain inflammation, Rg3 supplementation at 20 and 30 mg/kg oral doses significantly reduced inflammation by reducing the levels of inflammatory substances such as tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and IL-6 mRNA. 
- In rats with cognitive impairment, Rg3 treatment restored learning and memory functions. 
- A cell study also reported that Rg3 prevented brain inflammation by reducing inflammatory stimuli in the majority of brain tissues. 
- A study conducted on animal models of Alzheimer’s disease found that Rg3 can help prevent or slow the development of neurological disorders due to its anti-inflammatory activity in the brain. 
- A cell study found that Rg3 can help prevent Alzheimer’s disease by reducing the levels of abnormal protein structures in the brain. 
Lowers Risk of Heart Disease
Studies suggest that Rg3 offers cardioprotective effects:
- In rats, Rg3 administration protected against heart impairment. 
- In mice with heart injury, Rg3 treatment prevented the development of heart attack. 
- In rats, Rg3 delayed the progression of cardiovascular disease (CVD). 
Lowers Blood Pressure
Evidence shows that Rg3 has antihypertensive properties:
- In rats, daily oral administration of Rg3 lowered systolic and diastolic blood pressure. 
- A review of several studies showed that Rg3 is beneficial in treating hypertensive patients. 
Boosts Immune Function
Studies report that Rg3 also has immune-boosting properties:
- In an animal study, Rg3 treatment protected the animals from the lethality of the H1N1 virus. 
- In mice, Rg3 treatment stimulated an immune response by boosting the levels of specific immune cells such as immunoglobulin G. 
Helps Lose Weight
Evidence shows that Rg3 can help promote fat loss:
- A review of mice studies suggested that Rg3 could potentially reduce body fat percentage. 
- A study in obese mice showed that Rg3 treatment resulted in better metabolism. 
Accelerates Wound Healing
There’s also a good deal of evidence supporting the beneficial effects of Rg3 on wound healing.
- Studies showed that Rg3 consumption can help improve wound healing through its anti-inflammatory effects. [18-19]
- Studies show that Rg3 can help prevent the formation of raised scars after an injury. 
- A study also found that Rg3 can help prevent keloid scar formation by promoting collagen synthesis. 
A convincing number of high-quality studies found that Rg3 has anti-cancer effects:
- A study reported that Rg3 can be used as an anti-tumor medicine. 
- A study showed that Rg3 can help prevent esophageal cancer. 
- In mice bearing H460 lung cancer cells, 28-day oral treatment with Rg3 at 100mg/kg significantly reduced tumor growth. 
- In human esophageal cancer, Rg3 protected against esophageal cancer by promoting programmed cell death. 
Studies show that Rg3 also has antidepressant effects:
- In a mouse study, Rg3’s benefit on immunoregulation helped in reducing signs of depression. 
- A review of studies showed that Rg3 treatment reduced depressive symptoms in patients with low mood.
