Key Constituents
Characteristic constituents; verbenalin has a dopaminergic effect.
Antioxidant and anti-inflammatory constituents.
Supporting antioxidant and aromatic constituents.
The pungent phenolic constituents of the rhizome (notably 6-gingerol, which dehydrates to 6-shogaol on drying) responsible for ginger's antiemetic and anti-inflammatory activity; a standardized regimen of 84 mg/day gingerols/shogaols was effective against chemotherapy-induced nausea.
Pharmacological Actions

Safety, Cautions & Contraindications
Ginger is widely considered safe at culinary and conventional supplemental doses. At high doses (>5 g/day), ginger may cause heartburn, acid reflux, mouth irritation, and mild gastrointestinal discomfort. Ginger may modestly inhibit platelet aggregation and enhance the effects of anticoagulants (e.g., warfarin) — clinical significance at dietary amounts is low, but caution is warranted with high-dose supplementation alongside blood-thinning medications (Shalansky et al., 2007). May lower blood sugar — monitor closely if combining with antidiabetic medications.
Pregnancy: Ginger is among the most studied herbal remedies for pregnancy nausea. At doses up to 1 g/day, it is generally considered safe and effective for nausea and vomiting of pregnancy (NVP), based on multiple RCTs. The EMA monograph supports its use for NVP. Avoid doses >1.5 g/day during pregnancy due to theoretical concern about anticoagulant activity. Breastfeeding: generally considered safe at food amounts; limited data for medicinal doses (European Medicines Agency, 2012a).
Duke (2002) rates ginger as a triple-plus herb (+++) with strong clinical support (score 3) for antiemetic activity, including motion sickness, morning sickness, and postoperative nausea, and score 2 evidence for dyspepsia, diarrhea, and inflammation. Typical doses are 2-4 g dry rhizome per day or 500-1000 mg fresh root three times daily; Commission E approves ginger for dyspepsia and motion sickness. Ginger has antiplatelet properties and should be used with caution alongside anticoagulant medications (Duke, 2002).

Botanical Description
Slender, upright perennial herb with wiry, square, sparsely hairy stems and deeply lobed, toothed leaves. Tiny, pale lilac to pale purple, five-lobed flowers are borne sparsely along thin, wiry spikes at the ends of the branches, opening a few at a time.[11]
Rhizomatous perennial herb with narrow, lance-shaped leaves arising in two ranks from slender, reed-like pseudostems. Pale yellow-green flowers with purple markings are borne in a dense, cone-like spike on a separate short stalk arising directly from the rhizome, though ginger rarely flowers in cultivation. The branching, knobbly rhizome has a pale yellow interior and a characteristic pungent, spicy aroma.[1]
Habitat
Grows on dry waste ground, roadsides, field margins and disturbed soil; native to Europe, North Africa and temperate Asia and widely naturalised elsewhere.[11]
Believed native to tropical Southeast Asia; cultivated extensively throughout the tropics and subtropics (India, China, Nigeria, the Caribbean) in warm, humid conditions on well-drained, fertile soil.
Harvesting
The flowering aerial parts are cut in summer as the plant comes into flower and dried in a warm, shaded, airy place.
The rhizome is dug 8-10 months after planting, once the leaves have died back, for mature ('old') ginger with the fullest pungency, or earlier for milder young ('green') ginger; cleaned and used fresh or dried and ground.
Traditional Uses
Vervain has an ancient European reputation, reflected in its old names 'holy herb' and 'herb of the cross', as a calming nervine for nervous tension, anxiety and sleeplessness, and as a bitter digestive tonic; it has also traditionally been used topically and internally for aches, pains and mild inflammation.[11]
Ginger rhizome has one of the longest and most widespread medicinal histories of any spice, used across Chinese, Ayurvedic and Western herbal traditions as a warming digestive carminative, an antiemetic for nausea and motion sickness, and an anti-inflammatory remedy for joint pain; this traditional reputation is now supported by an extensive clinical evidence base, particularly for nausea (including pregnancy and chemotherapy-related) and osteoarthritis.[1]

Preparations
Not documented
Dried rhizome powder or standardised extract, taken as capsules for nausea or joint-pain studies.
Dosage
Not documented
Clinical trials for nausea commonly use around 1-1.5 g of dried rhizome powder daily, in divided doses (up to 1 g/day in pregnancy); osteoarthritis studies commonly use similar or somewhat higher doses. Educational reference only, not a prescription.
