Ginger Oleoresin Rhizome Extract
Also known as: Ginger, Halia, *Zingiber officinale*
Overview
Ginger is a widely recognized herbal supplement derived from the rhizome of *Zingiber officinale*, native to Southeast Asia and now cultivated globally. It has been extensively utilized for its culinary and medicinal properties, particularly for alleviating digestive issues and nausea. The rhizome contains bioactive compounds such as gingerols, shogaols, and zingerone, which contribute to its diverse therapeutic effects, including anti-inflammatory, antioxidant, antibacterial, antiviral, and potentially anticancer properties. The research surrounding ginger is mature, featuring numerous systematic reviews and meta-analyses that affirm its efficacy, particularly in reducing nausea and inflammation.
Benefits
Ginger supplementation offers significant health benefits, especially in managing nausea and inflammation. Systematic reviews indicate ginger effectively reduces chemotherapy-induced nausea and vomiting and exhibits anti-inflammatory properties by lowering inflammatory markers like CRP and IL-6. It has a pronounced positive impact on pregnant women experiencing nausea and can aid cancer patients. The evidence for its antimicrobial properties is less consistent, shown in studies with notable heterogeneity. Although promising results have emerged regarding cardiovascular and anti-diabetic effects, the research quality is not as robust. Overall, the benefits of ginger can be observed within days to weeks, with varying effect sizes reported for different conditions.
How it works
Ginger exerts its effects primarily through its bioactive compounds, particularly gingerols and shogaols, which inhibit pro-inflammatory enzymes such as COX-2 and modulate oxidative stress. These compounds activate molecular pathways like NF-κB, crucial in inflammatory responses. Ginger also has antimicrobial capabilities, impeding the growth of various microorganisms. Additionally, it enhances digestive health by reducing nausea and improving gastrointestinal function.
Side effects
Ginger is generally safe for consumption but can cause gastrointestinal upset in over 5% of users, presenting symptoms such as heartburn, diarrhea, and stomach pain. Allergic reactions may occur in about 1-5% of individuals, including hives and itching. Rarely, complications like bleeding disorders can arise due to ginger’s antiplatelet effects, particularly in individuals taking anticoagulants. Given these interactions, caution is advised for patients with bleeding disorders or those on diabetes medications. Pregnant women should consult healthcare providers prior to ginger use, although it is typically deemed safe in moderate amounts.
Dosage
The minimum effective dose for ginger typically starts at 250-500 mg per day, while optimal dosages for anti-inflammatory and antioxidant purposes range from 500-2000 mg per day. For anti-nausea effects, the suggested dosage is around 250-500 mg daily. There is no universally established maximum dose, but exceeding 3000 mg per day is discouraged due to a lack of substantiated safety within available studies. Ginger can be taken at any time, with pre-meal consumption recommended for nausea. It is available in various forms such as capsules, tablets, and teas, with enhanced absorption noted when taken with food.
