The use of herbs in North America has increased dramatically over the last decade and ginseng is one of the most widely-used ones. The name “ginseng” refers to American (Panax quinquefolius) as well as Asian or Korean ginseng (Panax ginseng) — both belong to the genus Panax and have a similar chemical makeup. Both Asian and American ginsengs contain ginsenosides, which are the substances thought to give ginseng its medicinal properties.
Ginseng is considered an “adaptogen” in herbal medicine, meaning it is an herb that helps the body to deal with various kinds of stress. Most ginseng studies have used Panax ginseng (Asian ginseng). There are some evidences suggesting that Panax ginseng may:
- help boost the immune system
- reduce the risk of cancer
- improve mental performance and well being
Laboratory studies in animals have found that American ginseng is effective in boosting the immune system, and as an antioxidant. Other studies show that American ginseng might have therapeutic potential for inflammatory diseases. A recent study from the University of Toronto just added one more disease that Ginseng may fight against, diabetes.
The researchers from the University of Toronto have found that taking American ginseng before a meal reduces blood sugar in people both with and without diabetes. The study appears in the April 9 issue of the Archives of Internal Medicine, a publication of the Journal of the American Medical Association(JAMA).
In the clinical study conducted by the UT researchers, the participants, both diabetic (Type 2) and non-diabetic, consumed capsules containing three grams of ground American ginseng either 40 minutes before or during a glucose test meal. Among participants with Type 2 diabetes, those who took the ginseng capsules experienced a 20% reduction in blood sugar levels compared to when they took placebo capsules. Among non-diabetic participants, similar reductions were only seen when the ginseng capsules were taken before, not together, with the test meal, suggesting that the timing of administration may be important.
Ginseng is a common herb as well as a food item in Asia. My favorite dish when visiting Seoul is Ginseng Chicken soup. With all these wonderful properties that the herb possesses, you might want to add this herb into your dietary regime too.

Human cognitive function tends to decline as we get older. Many researches have shown that risk of dementia is reduced by higher fruit and vegetable intake, and that cognitive function is better preserved in healthy older adults with a diet rich in plant-based foods. The consensus from the scientific community is that flavonoids, which are abundant in plants, are likely to be an important component in causing these effects.
In a study by the researchers from the University of Exeter of UK, 26 healthy adults aged 65-77 were divided into two groups: 12 were given concentrated blueberry juice, rich in flavonoids, — providing the equivalent of 230g of blueberries — once a day, while 14 received a placebo. Before and after the 12-week period, participants took a range of cognitive tests while an MRI scanner monitored their brain function and resting brain blood flow was measured.
Compared to the placebo group, the blueberry group showed significant increases in brain activity in brain areas related to the tests. Specifically, the study showed that with just 12 weeks of consuming 30ml of concentrated blueberry juice every day, brain blood flow, brain activation and some aspects of working memory were improved in this group of healthy older adults.
Blueberries are sweet, nutritious and wildly popular. Often labeled a “superfood,” they are low in calories and incredibly good for you. Blueberries are believed to contain one of the highestantioxidant content of commonly consumed fruits and vegetables with the main antioxidant compounds as flavonoids. The Exeter study seems to reinforce the existing belief that flavonoids benefits the brain function in older adults.

Ginkgo biloba has a long history of use in treating blood disorders and memory issues. In Chinese traditional medicine, Ginkgo biloba is often used for cognitive enhancement or to alleviate cognitive decline. The extract of the Ginkgo biloba is rich in antioxidants such as flavonoids and terpenoids. Laboratory studies have shown that the extract improves blood circulation by opening up blood vessels and making blood less sticky.
A recent study, published in Neural Regeneration Research, provides one additional explanation for the herb’s cognitive enhancing function. It seems that Ginkgo biloba is capable of promoting neural stem cells growth and therefore combat cognitive decline and impairments due to old age.
Led by Professor Jiwei Wang from Weifang Medical University, the research team studies the effect of Ginkgo biloba extract using a rat model with vascular dementia. In the experiment, rats were supplemented with Ginkgo biloba extract at 50mg/Kg per day for a period of time. Over the course of the treatment, the rats learning and memory abilities were assessed using the water maze. In addition, the endogenous neural stem cells in rats’ brain were measured.
Researchers found that Gingko biloba extract significantly improve learning and memory in the rats. In addition, the analysis showed that the number and proliferation of neuronal stem cells were significantly higher in rats given the extract. The researchers concluded that Ginkgo biloba extract may be used to treats memory loss and cognitive impairments in patients with senile dementia.

Goji berry, also called Lycium barbarum, Fructus lycii or Gouqizi, has been used as a traditional Chinese medicine (TCM) for thousands of years. In TCM literature, the herb is known for balancing “Yin” and “Yang” in the body, nourishing the liver and kidney and improving visual acuity.
Goji berry fruits have a variety of biological activities and pharmacological functions. The herb has been used in TCM for preventing and treating various chronic diseases including diabetes, hyperlipidemia, cancer, hepatitis, hypo-immunity function, thrombosis, and male infertility. The amazing medicinal property of the herb causes the Ministry of the Public Health of China to approve this delicious berry fruit to be marketed as a botanical medicine.
Modern research has revealed various active compounds in goji berry, including goji berry polysaccharides. Previous studies have shown that goji berry polysaccharides can enhance exercise endurance capacity, reduce fatigue and exhibit antioxidant activity in vitro and in vivo.
Regular physical exercise has many health benefits. Extensive research has shown that regular exercise lowers mortality, delays brain aging and reduces risk of cardiovascular disease, cancer, and diabetes. However, strenuous physical exercise is known to dramatically increase oxygen uptake, which leads to increased generation of free radicals and reactive oxygen species (ROS), such as superoxide and hydrogen peroxide. The free radicals and ROS are known to cause lipid peroxidation in cell membranes, DNA damage, and decreased antioxidant levels in muscle tissues and blood, leading to cellular and muscle damage.
Antioxidants are substances that help reduce the severity of oxidative stress either by forming a less active free radical or by quenching the oxidative reaction. Research suggests that dietary antioxidants may prevent muscle damage because they are able to detoxify some peroxides by scavenging ROS produced during exercise. Therefore, it only made sense that goji berry polysaccharides, due to their amazing antioxidant properties, may treat exercise-induced oxidative stress. It turns out that the animal studies showed exactly that.
To investigate such hypothesis, the researchers divided testing animals into four groups, i.e., one control group and three goji berry treated groups. The animals received the treatment for 28 days. On the day of the exercise test, animals were required to run to exhaustion on the treadmill. Body weight, endurance time, as well as oxidative stress indicators were measured.
The results showed that the body weight in goji berry treated groups were not significantly different from that in the control group before and after the experiment. After exhaustive exercise, the endurance time in goji berry treated groups was significantly prolonged compared with that in the control group. The oxidative stress indicators in the goji berry treated groups were significantly reduced compared with that in the control group. The collective results indicate that goji berry was effective in preventing oxidative stress after exhaustive exercise.
The take home message is that – do consider including goji berry in your exercise dietary regime. The herb not only tastes delicious but also may do wonders to your sports performance.

Human age—this fundamental rule of life is for the sake of species survival; and no —no one can stop it. Yes—we all know this at an abstract level. However, when it comes down to the individual level, none of us wants to age. For me personally, it’s really just about feeling great and looking great for as long as I can so I don’t have to face the reality of aging.
To slow down the aging process, we need to understand the process of aging first. Unfortunately, there isn’t one slam-dunk theory capturing the “truth” of aging. There are many scientific theories. In the next few posts, we will discuss each theory. This post is about the free radical theory of aging—the most popular of them all.
The free radical theory of aging: Free radicals, or Reactive Oxygen Species (ROD), are the toxic byproducts of normal cell metabolism in an oxygen-rich world, which is a world we are living in. Natural substances within cells such as antioxidants can clean up and neutralize the dangerous free radicals. Those free radicals that escape the cleanup process damage DNA, proteins and mitochondria (organelles within cells that produce energy). The resulting damage, which is called oxidative damage, accumulates over time, leading to genome instability, and is considered the primary cause of the aging process.
Many skincare and anti-aging products are developed based on the theory that oxidative damage is the most important aspect of the aging. Check out a drug store shelf—you will find tons of products with the word “antioxidant” in the product description. The common antioxidants in skincare products are Vitamin C, Vitamin E, Q10, and various phyto-antioxidants such as flavonoids, flavones, and polyphenols. All are effective with proper dosage and with regular consumption.
To counter oxidative damage caused aging, do load up antioxidants in your daily diet. Many fruits and vegetables are packed with antioxidants—because antioxidants are the plants’ natural defense against the oxidative damage to them. My personal favorite? Cocoa, i.e., dark chocolate! Dark chocolate is loaded with organic compounds that are biologically active and function as antioxidants. These include polyphenols, flavanols, catechins, among others. One study showed that cocoa and dark chocolate contained more antioxidant activity, polyphenols and flavanols than other fruits they tested including blueberries and Acai berries.1 Therefore, indulge in delicious taste of dark chocolate and fight the free radical caused aging as the an added benefit.
