Ginger has been valued for thousands of years for its medicinal and culinary properties and dozens different chemical components found in ginger root. Ginger is an n herbaceous perennial herb that grows annual stems about three feet tall. Ginger is an exceptional addition to any massage oil. It boosts the immune system and has amazing warming qualities. Ginger oil can help relieve aches and pain, as well as promote normal blood circulation. Mental fatigue and motion sickness don’t stand a chance with Ginger in hand. It also aids in poor circulation, colds, achy muscles and migraines.
Ginger produces a hot, fragrant kitchen spice. Young ginger rhizomes are juicy and fleshy with a very mild taste. They are often pickled in vinegar or sherry as a snack or cooked as an ingredient in many dishes. They can be steeped in boiling water to make ginger herb tea, to which honey is often added; sliced orange or lemon fruit may be added. Ginger can be made into candy, or ginger wine, which has been made commercially since 1740.
As the root is near the surface, you will often see small nobs at the soil line of your plant(s) that can be selectively cut for culinary use. Start harvesting about four months into the season and choose roots around the outer edge of the pot. At the end of the growing season when the leaves start to fade, uproot the plant and take a larger harvest if you need to.

Regulatory guidelines Has GRAS status.
Adverse skin reactions Undiluted ginger oil was moderately irritating to rabbits, but was not irritating to mice; tested at 4% on 25 volunteers it was neither irritating nor sensitizing. Low-level phototoxic effects reported for ginger oil are not considered significant. Oral administration of ginger oil dose-dependently weakened the delayed hypersensitivity response, so any allergic reaction from the oil is likely to be minimal.
Acute toxicity Ginger oil acute oral LD50 in rats >5 g/kg; acute dermal LD50 in rabbits >5 g/kg .
Subacute & subchronic toxicity In a 13 week oral toxicity study, ginger oil was administered to male and female rats at 100, 250 or 500 mg/kg/day. No adverse effects were seen, including mortality, decreased food consumption, changes in body weight or organ weights, hematological parameters, hepatic or renal function. No histopathological changes were noted in selected organs.
Antioxidant/pro-oxidant activity Ginger oil showed moderate antioxidant activity in lipid peroxidation tests, and high activity as a DPPH radical scavenge.
Carcinogenic/anticarcinogenic potential Ginger oil did not produce CA in CHL cells. Ginger oil dose-dependently inhibited aflatoxin B1-induced adducts in calf thymus DNA, in the presence of rat liver microsomes Lam & Zheng reported that ginger oil induced glutathione S-transferase activity to more than 2.5 times control level in mouse tissues, and Banerjee et al that it significantly induced both glutathione S-transferase and aryl hydrocarbon hydroxylase in mouse liver, all of these being indicative of anticarcinogenic activity. Ginger oil was cytotoxic to human prostate and lung cancer cells with IC50 values of 0.08%, 0.11% respectively, but it was not cytotoxic to breast cancer cells. (þ)-Limonene, b-sesquiphellandrene, and b-elemene display anticarcinogenic activity.
In addition to China and India, major ginger oil producers include England and Jamaica. CO2 extracts are also available.
