Ginseng refers to the roots of plants belonging to the genus Panax.

These plants are identified by specific chemical compounds called ginsenosides and gintonin. While many people use ginseng for health purposes, scientific research has not yet provided clinical evidence of its therapeutic effects. There is no substantial proof that ginseng can treat specific medical conditions. In the United States, the Food and Drug Administration (FDA) has not approved it to prevent or treat any disease. Instead, it is often sold as a dietary supplement.

Because supplement manufacturing can be inconsistent, some products have been found to contain unrelated filler compounds. It is also important to note that excessive use might cause adverse effects or interact with prescription drugs.

To understand how ginseng is prepared, one must look at the different processing methods. Fresh ginseng, or "green ginseng," is the raw, non-dried product. White ginseng is created by peeling the root and then drying it. This process reduces the water content to 12% or less. If the root is dried in the sun, it takes on a yellowish-white color. Red ginseng follows a different path through steaming and drying.

First, the peeled root is heated through steaming at standard boiling temperatures. After steaming, it is dried or sun-dried, which results in a reddish color. This steaming process makes red ginseng less vulnerable to decay than the white variety. Sometimes, the roots are marinated in an herbal brew, which makes them extremely brittle.

There are several distinct species of true ginseng within the Panax genus. Korean ginseng is known scientifically as Panax ginseng. Another type is Panax japonicus, which is Japanese ginseng. South China ginseng is called Panax notoginseng, and American ginseng is Panax quinquefolius. These plants generally prefer cooler climates. You can find them in the Korean Peninsula, Northeast China, the Russian Far East, Canada, and the United States. Some species, like Panax notoginseng, grow in warmer regions like Southwest China and Vietnam. Panax vietnamensis is recognized as the southernmost species in the genus.

Many other plants are called "ginseng" in common names, but they are not true ginseng. For example, Siberian ginseng belongs to the same family but not the same genus. It contains different active compounds called eleutherosides and has a woody root rather than a fleshy one.

History shows that humans have valued ginseng for a very long time. One of the earliest written records of ginseng as a medicinal herb is the Shen Nong Pharmacopoeia, written in China in 196 AD. In 1596, Li Shizhen included ginseng in his Compendium of Materia Medica. He described the plant as a "superior tonic." Historically, it was not used as a "cure-all" but specifically for patients with chronic illnesses or those recovering from sickness. By the 16th century, control over ginseng fields in China and Korea became a significant issue. Chinese folk tales even suggest that wild ginseng can transform into children. These stories claim a ginseng child might vanish if an adult ties a red ribbon around their feet.

Today, ginseng is a massive global industry with significant economic value. In 2013, global sales for the product exceeded $2 billion. China stands as the largest consumer of ginseng in the world. Most of the global supply comes from only four countries. In the early 21st century, China produced 44,749 tons of ginseng. South Korea produced 27,480 tons, Canada produced 6,486 tons, and the United States produced 1,054 tons. These four nations accounted for 99% of the world's 80,000 tons of ginseng.

While cultivated ginseng is widely available, wild ginseng is much rarer. Wild ginseng is considered endangered globally because it is harvested faster than it can grow and reproduce.

Growing ginseng requires specific biological steps and careful management. The seeds of the ginseng plant do not germinate immediately after the berries are harvested in autumn. Instead, the seeds usually do not sprout until the second spring following the harvest. To help them grow, they must undergo a process called stratification. This involves storing the seeds in a moist medium with both warm and cold treatments. Some scientists use plant tissue culture to create biomass more quickly. One method uses a "hairy-root" approach with Rhizobium rhizogenes. This method produces higher levels of ginsenosides compared to other cell-based approaches.

Understanding the connections between ginseng and human health requires looking at both benefits and risks. While it is used in Korean cuisine in soups, teas, and alcoholic beverages, users should be aware of potential interactions. For instance, ginseng may interact with blood thinners like warfarin by decreasing the drug's blood levels. It can also increase the effects of certain sedative medications. Long-term use has been linked to side effects such as insomnia, headaches, and digestive issues. Some users have also reported fluctuations in blood pressure or skin rashes. Because supplements are not regulated as strictly as drugs, the FDA has issued warnings to companies making false health claims.
