Ginseng ( /ˈdʒɪnsɛŋ/ ) [1] is the root of plants in the genus Panax , such as Korean ginseng ( P. ginseng ), South China ginseng ( P. notoginseng ), and American ginseng ( P. quinquefolius ), characterized by the presence of ginsenosides and gintonin. Ginseng is common in the cuisines and medicines of China and Korea.
Ginseng has been used in traditional medicine over centuries, though modern clinical research is inconclusive about its medical effectiveness. [2] [3] There is no substantial evidence that ginseng is effective for treating any medical condition and it has not been approved by the US Food and Drug Administration (FDA) to treat or prevent a disease or to provide a health benefit. [2] [3] [4] Although ginseng is sold as a dietary supplement, inconsistent manufacturing practices for supplements have led to analyses of some ginseng products contaminated with toxic metals or unrelated filler compounds, and its excessive use may have adverse effects or untoward interactions with prescription drugs. [2] [5]
One of the first written texts covering the use of ginseng as a medicinal herb was the Shen Nong Pharmacopoeia , written in China in 196 AD. In his Compendium of Materia Medica herbal of 1596, Li Shizhen described ginseng as a "superior tonic". However, the herb was not used as a "cure-all" medicine, but more specifically as a tonic for patients with chronic illnesses and those who were convalescing. [6]
Control over ginseng fields in China and Korea became an issue in the 16th century. [7]
In Chinese folk tales from the northeastern regions, ginseng is said to transform into children, often depicted with skyward-reaching braids, sometimes tied with red ribbons, and occasionally dressed in bellybands. In these stories, a ginseng child will typically enter a house to play with another child. However, if the adults tie a red ribbon around the child's feet, the child vanishes. When they follow the ribbon, they find it tied to a blade of grass, and upon digging, they uncover a ginseng root. [8]
Ginseng plants belong only to the genus Panax . [9] Cultivated species include Panax ginseng (Korean ginseng), Panax notoginseng (South China ginseng), Panax pseudoginseng (Himalayan ginseng), Panax quinquefolius (American ginseng), Panax trifolius (Dwarf ginseng), and Panax vietnamensis (Vietnamese ginseng). [10] Ginseng is found in cooler climates – Korean Peninsula, Northeast China, Russian Far East, Canada and the United States, although some species grow in warm regions – South China ginseng being native to Southwest China and Vietnam. Panax vietnamensis (Vietnamese ginseng) is the southernmost Panax species known.[ citation needed ]
Wild ginseng (Korean : 산삼; Hanja : 山蔘; RR : sansam;lit. mountain ginseng) grows naturally in mountains and is hand-picked by gatherers known as simmani (심마니). [11] The wild ginseng plant is almost extinct in China and endangered globally. [12] This is due to high demand for the product in recent years, leading to the harvesting of wild plants faster than they can grow and reproduce (a wild ginseng plant can take years to reach maturity [13] ). Wild ginseng can be processed to be red or white ginseng. [14] Wild American ginseng has long been used by Native Americans for medicine. [15] [16] [17] Since the mid-1700s, it has been harvested for international trade. [15] Wild American ginseng can be harvested in 19 states and the Appalachian Mountains but has restrictions for exporting. [15] [18] [19]
Cultivated ginseng (Korean : 인삼; Hanja : 人蔘; RR : insam;lit. human ginseng) is less expensive than the rarely available wild ginseng. [11]
Cultivated ginseng (Korean : 장뇌삼; Hanja : 長腦蔘; RR : jangnoesam) is planted on mountains by humans and is allowed to grow like wild ginseng. [11]
Ginseng seed normally does not germinate until the second spring following the harvest of berries in Autumn. They must first be subjected to a long period of storage in a moist medium with a warm/cold treatment, a process known as stratification. [20]
Fresh ginseng (Korean : 수삼; Hanja : 水蔘; RR : susam;lit. water ginseng), also called "green ginseng", is non-dried raw product. [21] Its use is limited by availability.[ citation needed ]
White ginseng (Korean : 백삼; Hanja : 白蔘; RR : baeksam;lit. white ginseng) is peeled and dried ginseng. [21] White ginseng is fresh ginseng which has been dried without being heated. It is peeled and dried to reduce the water content to 12% or less. [21] Drying in the sun bleaches the root to a yellowish-white color.[ citation needed ]
Red ginseng (traditional Chinese : 紅蔘; simplified Chinese : 红参; pinyin : hóngshēn; Korean : 홍삼; romaja : hongsam; lit. 'red ginseng') is steamed and dried ginseng, which has reddish color. [21] Red ginseng is less vulnerable to decay than white ginseng. [22] It is ginseng that has been peeled, heated through steaming at standard boiling temperatures of 100 °C (212 °F), and then dried or sun-dried. It is frequently marinated in an herbal brew which results in the root becoming extremely brittle.[ citation needed ]
Commercial ginseng is sold in over 35 countries, with China as the largest consumer. In 2013, global sales of ginseng exceeded $2 billion, of which half was produced by South Korea. [10] In the early 21st century, 99% of the world's 80,000 tons of ginseng was produced in just four countries: China (44,749 tons), South Korea (27,480 tons), Canada (6,486 tons), and the United States (1,054 tons). [10] All ginseng produced in South Korea is Korean ginseng (P. ginseng), while ginseng produced in China includes P. ginseng and South China ginseng (P. notoginseng). [10] Ginseng produced in Canada and the United States is mostly American ginseng (P. quinquefolius). [10] [23]
Ginseng may be included in energy drinks or herbal teas in small amounts or sold as a dietary supplement. [2] [3] [5] [24]
The root is most often available in dried form, either whole or sliced. In Korean cuisine, ginseng is used in various banchan (side dishes) and guk (soups), as well as tea and alcoholic beverages. [25] Ginseng-infused tea and liquor, known as insam cha (literally "ginseng tea") and insam-ju ("ginseng liquor") is consumed. [25] Ginseng leaves are also used to prepare foods and beverages. Leaves are used to prepare Asian soups, steamed with chicken or combined with ginger, dates, and pork, or are eaten fresh. [26] [27]
Although ginseng has been used in traditional medicine for centuries, there is no conclusive modern research that it has biological effects. [3] [28] Clinical research indicates there are no confirmed effects on memory, fatigue, menopause symptoms, and insulin response in people with mild diabetes. [3] A 2021 review indicated that ginseng had "only trivial effects on erectile function or satisfaction with intercourse compared to placebo". [29] As of 2023 [update] , there is no good evidence to indicate that taking ginseng causes any improvement of health or lowers the risk of any disease. [30] [31]
Although the roots are used in traditional Chinese medicine, the leaves and stems contain larger quantities of the phytochemicals than the roots, and are easier to harvest. [32] The constituents include steroid saponins known as ginsenosides, [33] but the effects of these ginseng compounds have not been studied with high-quality clinical research as of 2021, and therefore remain unknown. [2] [3] [28] [34]
As of 2019, the United States FDA and Federal Trade Commission have issued numerous warning letters to manufacturers of ginseng dietary supplements for making false claims of health or anti-disease benefits, stating that the "products are not generally recognized as safe and effective for the referenced uses" and are illegal as unauthorized "new drugs" under federal law. [35] [36] [37]
Ginseng supplements are not subjected to the same pre-market approval process in the US by the Food and Drug Administration (FDA) as pharmaceutical drugs. FDA mandates that manufacturers must ensure the safety of their ginseng supplements before marketing, without the necessity to substantiate the safety and efficacy of these supplements in a pre-market scenario. [38] Ginseng supplements can be complex, often containing multiple constituents. It is not uncommon to observe discrepancies between the ingredients listed on the product label and the actual components or their quantities present in the supplement. [38] While manufacturers can employ independent organizations to authenticate the quality of a product or its ingredients, such verification does not equate to a certification of the product's safety or effectiveness. These independent quality checks primarily focus on the integrity of the product in terms of its composition and do not extend to safety evaluations or purported clinical efficacy. [38]
Ginseng contains steroidal saponins known as ginsenosides, polyacetylenes, polysaccharides, peptidoglycans, and polyphenols, among diverse other phytochemicals, but the effects of these compounds in humans are unknown. [2] [30] [38]
Ginseng generally has a good safety profile and the incidence of adverse effects is minor when used over the short term. [2] [34] The FDA has classified ginseng as "generally recognized as safe" (GRAS), indicating its general tolerability in adult populations. [38]
The risk of interactions between ginseng and prescription medications is believed to be low, but ginseng may have adverse effects when used with blood thinners. [2] [3] Ginseng interacts with certain blood thinner medications, such as warfarin, leading to decreased blood levels of these drugs. [38] Ginseng can also potentiate the effects of sedative medications. [38] Concerns exist when ginseng is used over a longer term, potentially causing side effects such as skin rashes, [38] headaches, insomnia, and digestive problems. [2] [3] [34] The long-term use of ginseng may result in nervousness, anxiety, diarrhea, confusion, depression, or feelings of depersonalization, [38] nausea, and fluctuations in blood pressure (including hypertension). [2] [24] There have been reports of gynecomastia and breast pain associated with ginseng use. [38] Other side effects include breast pain and vaginal bleeding. [2] [24] [38] As of 2023, there is a lack of data regarding the safety and efficacy of ginseng in lactating mothers and infants. [2] Given its potential estrogenic activity and the absence of safety data during lactation, ginseng is not recommended for use during breastfeeding. [2] [38] Ginseng also has adverse drug reactions with phenelzine, [39] and a potential interaction has been reported with imatinib, [40] resulting in hepatotoxicity, and with lamotrigine. [41]
The common ginsengs (P. ginseng and P. quinquefolia) are generally considered to be relatively safe even in large amounts. [42] One of the most common and characteristic symptoms of an acute overdose of P. ginseng is bleeding. Symptoms of mild overdose may include dry mouth and lips, excitation, fidgeting, irritability, tremor, palpitations, blurred vision, headache, insomnia, increased body temperature, increased blood pressure, edema, decreased appetite, dizziness, itching, eczema, early morning diarrhea, bleeding, and fatigue. [9] [42]
Symptoms of severe overdose with P. ginseng may include nausea, vomiting, irritability, restlessness, urinary and bowel incontinence, fever, increased blood pressure, increased respiration, decreased sensitivity and reaction to light, decreased heart rate, cyanotic (blue) facial complexion, red facial complexion, seizures, convulsions, and delirium. [9] [42]
The English word "ginseng" comes from the Teochew Chinese jîn-sim (人蔘; where this transliteration is in Pe̍h-ōe-jī). The first character 人 (pinyin rén; Modern Standard Mandarin pronunciation: [ʐə̌n] or [ɻə̌n] ) means "person" [43] and the second character 蔘 (pinyin :shēn; MSM: [ʂə́n] ) means "plant root" in a forked shape. [44]
The Korean loanword insam comes from the cultivated ginseng (Korean : 인삼; Hanja : 人蔘; RR : insam;lit. human ginseng), which is less expensive than wild ginseng.[ citation needed ]
The botanical genus name Panax, meaning "all-healing" in Greek, shares the same origin as "panacea" and was applied to this genus because Carl Linnaeus was aware of its wide use in Chinese medicine as a muscle relaxant.[ citation needed ]

True ginseng plants belong only to the genus Panax. [9] Several other plants are sometimes referred to as ginseng,but they are from a different genus or even family. Siberian ginseng is in the same family,but not genus,as true ginseng. The active compounds in Siberian ginseng are eleutherosides,not ginsenosides. Instead of a fleshy root,Siberian ginseng has a woody root.
Herbal teas, technically known as herbal infusions, and less commonly called tisanes, are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. Often herb tea, or the plain term tea, is used as a reference to all sorts of herbal teas. Many herbs used in teas/tisanes are also used in herbal medicine and in folk medicine.
An aphrodisiac is a substance alleged to increase libido, sexual desire, sexual attraction, sexual pleasure, or sexual behavior. These substances range from a variety of plants, spices, and foods to synthetic chemicals. Natural aphrodisiacs, such as cannabis or cocaine, are classified into plant-based and non-plant-based substances. Synthetic aphrodisiacs include MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects. Aphrodisiacs that contain hallucinogenic properties, such as bufotenin, have psychological effects that can increase sexual desire and sexual pleasure. Aphrodisiacs that have smooth muscle relaxing properties, such as yohimbine, have physiological effects that can affect hormone concentrations and increase blood flow.
Chinese herbology is the theory of traditional Chinese herbal therapy, which accounts for the majority of treatments in traditional Chinese medicine (TCM). A Nature editorial described TCM as "fraught with pseudoscience", and said that the most obvious reason why it has not delivered many cures is that the majority of its treatments have no logical mechanism of action.
Herbal medicine is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. With worldwide research into pharmacology, some herbal medicines have been translated into modern remedies, such as the anti-malarial group of drugs called artemisinin isolated from Artemisia annua, a herb that was known in Chinese medicine to treat fever. There is limited scientific evidence for the safety and efficacy of many plants used in 21st-century herbalism, which generally does not provide standards for purity or dosage. The scope of herbal medicine sometimes includes fungal and bee products, as well as minerals, shells and certain animal parts.
The Panax (ginseng) genus belongs to the Araliaceae (ivy) family. Panax species are characterized by the presence of ginsenosides and gintonin. Panax is one of approximately 60 plant genera with a classical disjunct east Asian and east North American distribution. Furthermore, this disjunct distribution is asymmetric as only two of the ~18 species in genus are native to North America.
Eleutherococcus senticosus is a species of small, woody shrub in the family Araliaceae native to Northeastern Asia. It may be colloquially called devil's bush, Siberian ginseng, taiga root, eleuthero, ciwujia, Devil's shrub, shigoka, touch-me-not, wild pepper, or kan jang. E. senticosus has a history of use in folklore and traditional Chinese medicine. Root extracts of E. senticosus are sold as a dietary supplement or cosmetic, usually under the name Siberian ginseng.
Angelica sinensis, commonly known as dong quai or female ginseng, is a herb belonging to the family Apiaceae, indigenous to China. Angelica sinensis grows in cool high altitude mountains in East Asia. The yellowish brown root of the plant is harvested in the fall and is a well-known Chinese medicine which has been used for thousands of years.
Panax ginseng, ginseng, also known as Asian ginseng, Chinese ginseng or Korean ginseng, is a species of plant whose root is the original source of ginseng. It is a perennial plant that grows in the mountains of East Asia.
Adaptogens or adaptogenic substances are used in herbal medicine for the purported stabilization of physiological processes and promotion of homeostasis.
Withania somnifera, known commonly as ashwagandha, is an evergreen shrub in the Solanaceae or nightshade family that grows in Nepal, India, the Middle East, and parts of Africa. Several other species in the genus Withania are morphologically similar.
Samgye-tang, or ginseng chicken soup, meaning ginseng - chicken - soup in Korean, consists primarily of a whole young chicken (poussin) or quail filled with garlic, rice, jujube and ginseng. Samgye-tang is a Korean traditional soup for body health. Samgye-tang is a representative summer health food. Soup made with chicken that is slightly larger than the chick is called Yeonggye Baeksuk, and the chicken is divided into half is called Banggye-tang.
Gynostemma pentaphyllum, also called jiaogulan, is a dioecious, herbaceous climbing vine of the family Cucurbitaceae widely distributed in South and East Asia as well as New Guinea.
Panax notoginseng is a species of the genus Panax, and it is commonly referred to in English as Chinese ginseng or notoginseng. In Chinese it is called tiánqī, tienchi ginseng, sānqī or sanchi, three-seven root, and mountain plant. P. notoginseng belongs to the same scientific genus as Panax ginseng. In Latin, the word panax means "cure-all", and the family of ginseng plants is one of the best-known herbs.
Nectria radicicola is a plant pathogen that is the causal agent of root rot and rusty root. Substrates include ginseng and Narcissus. It is also implicated in the black foot disease of grapevine. It is of the genus Nectria and the family Nectriaceae. N. radicicola is recognizable due to its unique anatomy, morphology, and the formation of its anamorph Cylindrocarpon desructans.
Ginsenosides or panaxosides are a class of natural product steroid glycosides and triterpene saponins. Compounds in this family are found almost exclusively in the plant genus Panax (ginseng), which has a long history of use in traditional medicine that has led to the study of pharmacological effects of ginseng compounds. As a class, ginsenosides exhibit a large variety of subtle and difficult-to-characterize biological effects when studied in isolation.
Economic botany is the study of the relationship between people and plants. Economic botany intersects many fields including established disciplines such as agronomy, anthropology, archaeology, chemistry, economics, ethnobotany, ethnology, forestry, genetic resources, geography, geology, horticulture, medicine, microbiology, nutrition, pharmacognosy, and pharmacology. This link between botany and anthropology explores the ways humans use plants for food, medicines, and commerce.
American ginseng is a species of flowering plant in the ivy family Araliaceae. It is native to eastern North America and has been introduced into China. The specific epithet quinquefolius means "five-leaved", which refers to the typical number of leaflets per leaf. It is one of a group of taxa known as "ginseng".
Ginseng tea, or insam-cha, is a traditional Korean tea made with ginseng. While it is called a tea, ginseng tea does not contain tea leaves. It is a herbal tea infusion made out of the ginseng plant's root. Ginseng is a perennial herb derived from the aromatic root of Panax Ginseng Meyer, also known as Korean ginseng. Ginseng grows in shady forests that are cool and damp. It is a slow-growing plant and is difficult to cultivate. It can take four to six years before the root is ready to be harvested. Ginseng roots have a forked and twisted appearance that somewhat resembles the human body.
Pseudoginsenoside F11 is a chemical natural product found in American ginseng but not in Asian ginseng, although it has similar properties to the Asian ginseng compound ginsenoside Rf. The molecule is a triterpenoid saponin member of the dammarane family and contains a four-ring rigid skeleton. Compounds in the ginsenoside family are found almost exclusively in plants of the genus Panax. A wide variety of difficult-to-characterize in vitro effects have been reported for the compounds in isolation. Pseudoginsenoside F11 and its derivatives are sometimes referred to as having an ocotillol-type skeleton structure.
