Key Constituents
Characteristic phenylpropanoid glycosides largely unique to Rhodiola rosea, used as a standardisation marker for commercial extracts.
Phenylethanoid glycosides considered key adaptogenic and antioxidant constituents.
Contribute to the anti-inflammatory and antioxidant activity of the root.
Steroidal lactones considered the principal bioactive compounds, responsible for most of the plant's adaptogenic, anti-inflammatory and anticancer research interest.
Minor tropane-type alkaloids contributing to the traditional sedative reputation.
Glycowithanolides linked to adaptogenic and immunomodulatory activity.

Safety, Cautions & Contraindications
Generally well tolerated. May cause agitation, insomnia, or vivid dreams in sensitive individuals — take in the morning. Avoid in manic episodes or severe anxiety. Theoretical interactions with MAOIs, SSRIs, and CNS stimulants. Avoid during pregnancy and breastfeeding.
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.
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
Succulent perennial herb (Crassulaceae), 15-40 cm tall, with a thick, fleshy, branching rhizome that has a rose-like fragrance when cut - the origin of the name 'rosea'. Leaves are fleshy, greyish-green, oval to oblong. Small yellow (occasionally reddish) flowers are clustered in dense terminal heads; the species is dioecious, with separate male and female plants. Fruit follicles turn red as they ripen.[3]
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]
Habitat
Native to arctic and mountainous regions of Europe, Asia and North America (circumpolar), growing in cold, rocky, high-altitude or high-latitude terrain - cliffs, rocky slopes and tundra - tolerating harsh, exposed conditions.[3]
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
Rhizome and root are dug from plants at least a few years old (traditionally 4-5 years), typically in autumn, then cleaned and dried. Wild populations grow slowly, so cultivated sources are increasingly preferred for sustainability.[3]
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]
Traditional Uses
Rhodiola has a long tradition of use across Scandinavian, Russian and Central Asian folk medicine as a tonic for cold-climate hardiness, physical endurance and mental stamina. It is classified as a modern 'adaptogen', and clinical trials support benefits for stress-related fatigue, mood and cognitive performance.[1, 3]
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
Dosage
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
Pairings
Rhodiola and eleuthero (Siberian ginseng) are classic adaptogens combined in traditional and studied fixed formulas to build resistance to stress and fatigue; used together their stress-protective effects are complementary.[17, 18]
Rhodiola and schisandra are adaptogens co-formulated in clinically studied combinations for stress, fatigue and mental performance; combined use is intended to be synergistic rather than harmful.[17, 18]
Both ashwagandha and valerian are calming, sleep-promoting herbs; using them together may add to drowsiness and sedation, so take care especially before driving or when using other sedatives.[1, 23]
