The Zoi™ Biomedical & TCM Details

The Zoi™ is comprised of herbs, which research has shown to haveanti-tumor, anti-inflammatory, immune-modulating, anti-aging, and disease prevention properties. 

The herbs included in The Zoi™ are known for broad therapeutic and health-enhancing properties, and have potential to prevent disease. The Zoi™ is appropriate to use in combination with conventional medical therapies, but should be discussed with your doctor.

Most of the herbs in The Zoi™ have anti-inflammatory (1, 3, 5, 7, 8, 9, 11, 14) and immune regulating effects (3, 4, 5, 12). Studies with gotu kola, specifically, have resulted in improvements in age-related conditions like hypertension, peripheral neuritis, insomnia, loss of appetite, constipation and age-related cognitive decline in the elderly (14).

Cordyceps, fleeceflower, wolfberry, astragalus, bupleurum, and magnolia bark have anti-tumor functions (1, 2, 3, 4, 5, 6). Cordyceps, specifically, has been used as an adjunct to conventional anti-cancer therapies in humans, supporting the immune system and body through cancer treatment. Iin animal studies, cordyceps extract has been shown to directly kill cancer cells (7,8). Bioactive components of wolfberry and magnolia bark have been reported to enhance tumor regression when used in combination with other treatments (3, 4, 9) Magnolia bark extracts have been shown to cross the blood-brain barrier to exert anti-tumor effects (6), and wolfberry and bupleurum have also exhibited potential anti-tumor functions (6, 3). Astragalus has been shown to counteract side effects of chemotherapy (5).

Antioxidants(vitamins C and E, carotene, lycopene and other substances) are believed to play a role in preventing diseases such as cancer, cardiovascular disease, Alzheimer’s and macular degeneration. There is good evidence that wolfberry is rich in the antioxidants, vitamin C and zeaxanthin (3). Components of other herbs in The Zoi™ also have antioxidant functions, including fleeceflower, cordyceps, magnolia bark, astragalus and gotu kola (1, 2, 9, 10, 14). In one human study, a group of elderly took 50 g/day of wolfberry fruit for 10 days and showed significant increases in the levels of blood antioxidants (48%) and hemoglobin (12%), and a 65% decrease in lipid peroxides.

Fleeceflower and wolfberry have been shown to decrease blood sugar and lipidsin animal tests (1, 3); and wolfberry, magnolia bark and cordyceps seem to be beneficial to the cardiovascular system. Cordyceps, specifically, has been associated with blood cholesterol and triglyceride reduction. In one randomized trial, 95% of the patients treated with 3 g/day saw improvement in their blood sugar profiles, while the control group showed only 54% improvement with treatment by other methods (7). In another study, patients suffering from chronic heart failure were given cordycepsin combination with their conventional treatments (digoxin, hydrochlorothiaside, dopamine, and dobutamine) and reported an increase in the overall quality of life (physical condition, mental health, sexual drive, and cardiac function) compared to the control group (7). A gotu kola component was used in a human study and showed a statistically significant decrease in circulating endothelial cells, indicating positive effects on the integrity of blood vessel walls. (14). In another human study, significant impacts were noted on kidney function as measured by ankle edema, as well as positive effects on microcirculation and capillary permeability in patients (14).

Neuro-protection is an effect that may result in recovery or regeneration of the nervous system, its cells, structure and function. Wolfberry and cordyceps have exhibited some of these activities, and studies indicate wolfberry to be protective of, and regenerative to the eye(3, 9). Perhaps some of these neuroprotective functions are at the root of some of these herb’s influence on stress and anxiety. Some animal studies have shown that wolfberry protects the nervous system. Magnolia bark improves stress tolerance affecting symptoms of anxiety and depression (9, 13). Several gotu kola studies have indicated positive effects on the brain and nervous system. One double-blind, placebo-controlled human study noted anti-anxiety effects of gotu kola, and another study in elderly subjects showed significant improvements in cognition and mood with gotu kola (14).
