Key Constituents

Ginsenosides (panaxosides)^[3]

The principal bioactive triterpene saponins of the root, considered responsible for most of ginseng's adaptogenic, neuroprotective and immunomodulatory activity; the ratio of protopanaxadiol- to protopanaxatriol-type ginsenosides differs between fresh, white and red ginseng.

Ginsenosides / eleutherosides

Polysaccharides (panaxans)^[7]

Contribute to the immunomodulatory activity of the root.

Polysaccharides

Volatile oil and phenolic compounds^[7]

Minor constituents contributing to the aroma and antioxidant activity.

Essential (volatile) oilPhenolic compounds

Withanolides (withaferin A, withanolide A)^[5]

Steroidal lactones considered the principal bioactive compounds, responsible for most of the plant's adaptogenic, anti-inflammatory and anticancer research interest.

Alkaloids (withanine, somniferine)^[5]

Minor tropane-type alkaloids contributing to the traditional sedative reputation.

Safety, Cautions & Contraindications

Safety note^{[11, 12, 13]}Caution

Generally well tolerated in short-term use (up to 3 months). May cause insomnia, headache, or gastrointestinal upset at high doses. Avoid during pregnancy and breastfeeding. May interact with warfarin, MAOIs, and diabetic medications. Not recommended for continuous use without breaks.

Safety note^{[11, 12, 13, 14]}Caution

Duke (2002) rates Korean/Oriental ginseng (Panax ginseng) as highly active with clinical support for adaptogenic, immunostimulant, and performance-enhancing effects. Commission E approves standardized ginseng root extract (4–7% ginsenosides) as a tonic for fatigue and during convalescence. Dose: 200–600 mg standardized extract daily. Duke cautions about 'Ginseng Abuse Syndrome' (GAS) with overdose — symptoms include hypertension, insomnia, edema, and nervousness. Drug interactions are notable: ginseng potentiates MAOIs and may interact with warfarin, digoxin, and stimulants. Cycle use (2–3 weeks on, 2 weeks off) is recommended (Duke, 2002).

Safety note^{[12, 13, 14, 15, 16, 17, 18, 19]}Caution

Generally well-tolerated in clinical trials at doses up to 600 mg/day for up to 12 weeks. Common side effects may include mild drowsiness, gastrointestinal upset, and diarrhea at higher doses. Contraindicated during pregnancy due to potential abortifacient effects. May interact with sedatives, immunosuppressants, thyroid medications, and blood sugar medications. People with autoimmune diseases, hyperthyroidism, or scheduled for surgery should consult healthcare providers before use. May cause allergic reactions in sensitive individuals. Not recommended for children without medical supervision.

Safety note^{[12, 13, 14, 15, 16, 17, 18, 19, 20]}Caution

Duke (2002) classifies ashwagandha activities primarily at the experimental level (score 1), with adaptogenic, sedative, immunostimulant, and anti-inflammatory actions demonstrated in animal and in vitro models. Root preparations are used at 2–3 g powdered root three times daily, or 150–300 mg of standardized extract. Importantly, the plant has documented abortifacient and antifertility properties in animal studies, and its use should be avoided during pregnancy. It may potentiate the effects of barbiturates and sedatives (Duke, 2002).

Botanical Description

Slow-growing perennial herb (Araliaceae), 30-60 cm tall, harvested at 4 years of age or older. A single erect stem bears a whorl of palmately compound leaves, each with 3-5 toothed leaflets, at its top. Small greenish-white flowers are borne in a single terminal umbel, followed by small red berries. The fleshy, often forked or human-shaped taproot - the origin of the name 'ginseng' ('renshen', man-root) - is the medicinal part.^[3]

Height: 30-60 cm

Habit: Slow-growing perennial herb, single erect stem

Leaves: Palmately compound, whorled at the stem top, 3-5 toothed leaflets per leaf

Flowers: Small, greenish-white, in a single terminal umbel

Stem: Single, erect

Root: Fleshy, often forked, human-shaped taproot - the medicinal part

Fruit: Small red berries

Flowering Period: May-June

Erect, branching perennial shrub with soft, downy, oval to lance-shaped leaves. Small, inconspicuous, greenish-yellow bell-shaped flowers are borne in the leaf axils, followed by a small orange-red berry enclosed in a papery, lantern-like calyx, giving rise to the name 'winter cherry'.^[5]

Height: 0.3-1.5 m

Habit: Erect, branching perennial shrub

Leaves: Soft, downy, oval to lance-shaped

Flowers: Small, inconspicuous, greenish-yellow, bell-shaped

Stem: Erect, branching, downy

Root: Long, thick, tapering, pale brown root (the medicinal part), aromatic with a distinctive horse-like smell (the source of the name ashwagandha)

Fruit: Small orange-red berry enclosed in a papery, lantern-like calyx

Flowering Period: Summer to autumn

Habitat

Native to the cool-temperate deciduous mountain forests of Manchuria, Korea and the Russian Far East. Historically wild-harvested, it is now predominantly cultivated, mainly in Korea and China, under artificial shade for several years before harvest.^[1]

Native to the drier regions of India, the Middle East and parts of Africa; cultivated in warm, semi-arid climates on well-drained soils, notably in central and western India.^[5]

Harvesting

The root is harvested after at least 4-6 years of growth, once its ginsenoside content is fully developed. Roots are either air-dried as 'white ginseng' or steamed and then dried as 'red ginseng', a processing step that alters the ginsenoside profile.^[3]

Parts: Root

Season: After 4-6+ years of cultivation

The root is dug in winter from plants around one year old, when withanolide content is highest, then cleaned, cut and dried; the leaves are picked through the growing season.^[5]

Parts: Leaf, Root

Season: Root in winter, from around one-year-old plants; leaf through the growing season

Traditional Uses

Ginseng is one of the most celebrated tonic herbs of East Asian traditional medicine, used for millennia as a general adaptogen to restore vitality, support recovery from illness and improve stamina and cognitive performance. Modern clinical research supports adaptogenic, immunomodulatory, antioxidant, neuroprotective and mild antidiabetic effects consistent with this traditional use.^{[1, 7]}

Ashwagandha root is one of the most important rasayana (rejuvenative) tonics of Ayurvedic medicine, traditionally used to build strength and vitality, support healthy stress response, and promote restful sleep; this traditional adaptogenic reputation is now supported by clinical trials of standardised root extract for stress, sleep and physical performance.^{[1, 5]}

Preparations

Standardised root extract (capsule)^{[11, 12, 13]}

Commission E-recognised standardised extract (4-7% ginsenosides), the most clinically studied preparation.

Red ginseng (steamed and dried root)^[3]

Traditional processed form (steamed then dried), which alters and concentrates the ginsenoside profile compared with white (unprocessed) ginseng.

Standardised extract^{[1, 5]}

Root extract standardised to withanolide content, taken as capsules or tablets; the form used in most clinical stress, sleep and performance studies.

Dosage

Standardised extract^{[11, 12, 13]}

Duke (2002) and Commission E guidance: 200-600 mg of standardised extract (4-7% ginsenosides) daily, used cyclically (2-3 weeks on, 2 weeks off) rather than continuously. Educational reference only, not a prescription.

Standardised extract^[1]

Clinical trials for stress and sleep commonly use around 300-600 mg of standardised root extract daily, in divided doses, over several weeks. Educational reference only, not a prescription.

Drug Class Interactions

Safety note^{[15, 16]}Caution

Drug Class: anticoagulants-antiplatelets

Mechanism: Ginseng may reduce the anticoagulant effect of warfarin (lower INR); a randomized trial of American ginseng showed a reduced INR. Monitor anticoagulation closely.
