AI-Generated response:

Is ginger a good treatment for nausea?

Answer generated on June 4, 2024

The AI-generated responses are for illustration purposes only and should not be used for medical purposes.

Yes, ginger is considered a good treatment for nausea, particularly for pregnancy-induced nausea and chemotherapy-induced nausea and vomiting.

  • Ginger is recommended by the American College of Obstetricians and Gynecologists (ACOG) as a first-line nonpharmacologic option for nausea during pregnancy.[1]

  • For pregnancy-induced nausea, a dosage of 250 mg orally four times per day, not exceeding 1 gram per day, is suggested.[1]

  • Ginger has shown effectiveness in reducing nausea related to chemotherapy, as evidenced by improvements in nausea-related quality of life and a lower incidence of delayed nausea and vomiting in clinical trials.[2]

  • Ginger is generally recognized as safe (GRAS) by the FDA, but it is important to note that herbal products like ginger are not regulated as strictly as pharmaceuticals, which may lead to variability in potency and purity.[1]

  • While ginger is effective in reducing nausea, studies have not shown significant reductions in vomiting episodes.[1][3]

Additional info

Ginger's antiemetic properties are attributed to its pharmacological actions, including anticholinergic and antihistaminic effects, although its exact mechanism in preventing motion sickness and nausea is not fully understood.[1] It is also important for healthcare providers to consider the source and preparation of ginger, as these can affect the concentration of active ingredients. Clinical trials have generally used standardized ginger preparations to ensure consistent dosing and results. When recommending ginger, physicians should advise patients on appropriate dosing and consider potential interactions with other medications, especially in patients with underlying health conditions or those who are pregnant. Always consider the individual patient's context and medical history when integrating nonpharmacologic treatments like ginger into a therapeutic regimen.

Ginger, Zingiber officinale, Elsevier ClinicalKey Drug Monograph Content last updated: May 3, 2024

Description Ginger is a dietary supplement derived from the underground stem (rhizome) of the perennial plant Zingiber officinale Roscoe. Usually grown in warmer climates, ginger is often referred to by its country of origin. Jamaican ginger, African ginger, and Cochin ginger (China) contain different concentrations of the active ingredient(s). Ginger is chemically classified as an essential oil with pungent principles. The dried rhizome contains approximately 1 to 3% volatile oil which is the source of ginger's characteristic aroma; an oleoresin contains the pungent properties. Ginger has been in use as a digestive aid, spice, and flavoring agent for over 20 centuries. Primarily used as a spice or a dietary supplement, ginger has been used for the prevention of motion sickness. The American College of Obstetricians and Gynecologists (ACOG) guidelines state that ginger may be considered as a first-line nonpharmacologic option for nausea/vomiting during pregnancy; use of ginger may reduce nausea in pregnant women but is not shown to be effective at reducing vomiting episodes. The German Commission E lists anorexia as an indication for a fixed combination of Ginger root, Gentian root, and Wormwood. Reports of neurotoxicity associated with Jamaican ginger in the 1930s were due to an adulterant used in the extract. Ginger is listed in the USP and is Generally Recognized As Safe (GRAS) by the FDA. NOTE: In the U.S., herbal products and dietary supplements are marketed under the Dietary Supplement and Health Education Act of 1994 (DSHEA). Consequently, scientific data supporting claimed benefit(s) are not always available for dietary supplements as they are for traditional pharmaceuticals since supplements are not regulated as drugs. Consumers should also note that rigid quality control standards are not required for these products and substantial variability can occur in both the potency and the purity of these products.

Indications And Dosage Oral dosage Adult pregnant females: 250 mg PO 4 times per day. Suggested Max: 1 gram/day. The American College of Obstetricians and Gynecologists (ACOG) states that ginger may be considered as a first-line nonpharmacologic option. Per ACOG, meta-analyses and systematic reviews of controlled trials (randomized and nonrandomized) have found that ginger was associated with improvements in nausea, but studies have not shown reductions in vomiting.

Pregnancy The American College of Obstetricians and Gynecologists (ACOG) states that ginger can be considered as a first-line nonpharmacologic option for nausea/vomiting during pregnancy. While the German Commission E does not recommend the use of ginger during pregnancy, it lists no specific contraindications related to pregnancy. Controlled trials to date during human pregnancy have not indicated that ginger causes harm to the mother or fetus or other severe toxicity; the dose of ginger ingested during these trials (i.e., no more than 1 gram of fresh root) has generally been below the amounts of ginger used as a spice in various foods. Females should be advised not to exceed normal dietary intakes of ginger.

Mechanism Of Action Ginger posesses antiemetic, anti-inflammatory, analgesic, and cardiotonic properties. Ginger is a cholagogic agent that promotes the flow of bile into the intestine, especially through contraction of the gallbladder. Pharmacologically active components of the oleoresin include gingerols, a class of structurally similar cardioactive compounds, and shogaols. In vitro, gingerols produce concentration-dependent inotropic effects through activation of sarcoplasmic reticulum calcium adenosine triphosphatase (SR Ca2+ATPase). • ** Antiemetic Actions:** Ginger's mechanism of action for the prevention of motion sickness and nausea is not clear. In animal studies, ginger produced antispasmodic effects and exhibited anticholinergic and antihistaminic action. Ginger increases salivation and stimulates intestinal motility through increased tone and peristalsis of the intestines in humans. However, the results of a double-blind randomized crossover trial of healthy volunteers demonstrated no measurable effect on gastric emptying. Galanolactone, a diterpenoid constituent of ginger, demonstrated activity as a 5HT3 antagonist in vitro. Receptors for 5HT3 are located on intestinal vagal nerve terminals and in the chemoreceptor trigger zone. • ** Anti-inflammatory Actions:** Ginger inhibits thromboxane synthetase and is a prostacyclin agonist. Prostaglandins induce vasodilation and increase tissue permeability, which, in turn, promote the influx of fluids and leukocytes. Ultimately, the classic symptoms of inflammation result: swelling, redness, warmth, and pain. It is believed that at least one of the mechanisms by which ginger produces its antiinflammatory effects is through the inhibition of prostaglandin and leukotriene biosynthesis. Through this dual inhibition of eicosanoid biosynthesis, ginger decreases capillary permeability, thus reducing swelling and the influx of inflammatory mediators.

Effect of a Standardized Ginger Root Powder Regimen on Chemotherapy-Induced Nausea and Vomiting: A Multicenter, Double-Blind, Placebo-Controlled Randomized Trial. Journal of the Academy of Nutrition and Dietetics. 2024;124(3):313-330.e6. doi:10.1016/j.jand.2023.09.003. Publish date: March 5, 2024

RESULTS: One hundred three participants (ginger: n = 52; placebo: n = 51) were enrolled and analyzed. There was clinically relevant evidence against the null hypothesis, favoring ginger, in change scores for nausea-related QoL (F[df] = 9.34[1,101]; P = 0.003; partial η2 = 0.09), overall CINV-related QoL (F[df] = 12.26[1,101]; P < 0.001; partial η2 = 0.11), delayed nausea severity (F[df] = 9.46[1,101]; P = 0.003; partial η2 = 0.09), and fatigue (F[df] = 10.11[1,101]; P = 0.002; partial η2 = 0.09). There was a clinically meaningful lower incidence of delayed nausea and vomiting in the ginger group at Cycle 2 (53% vs 75%; P = 0.020 and 4% vs 27%; P = 0.001, respectively) and Cycle 3 (49% vs 79%; P = 0.002 and 2% vs 23%; P = 0.001, respectively).
