- Note: Alpinia should not be confused with ginger (Zingiber officinale).
- Alpinia is a large genus from the ginger family (Zingiberaceae). Alpinia has been known in Europe for several centuries longer than its botanical origin. It was recognized in 1870, when specimens were examined that had been found near Tung-sai, in the extreme south of China, and later, on the island of Hainan.
- Traditional uses have included treatment of flatulence (gas), dyspepsia (stomach upset), vomiting, high blood pressure, gastrointestinal complaints, and sea sickness.
- Alpinia has been studied for its diuretic (increasing urine flow) effects. Although alpinia is generally believed to be well-tolerated, safety is not well studied. Currently, there is not enough available scientific evidence for or against the use of alpinia for any indication.
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Limited evidence suggests that extract of alpinia may increase diuresis (the secretion of urine). However, some laboratory studies contradict these findings and more studies are needed in this area.
Alpinia, also known as Chinese ginger, has been studied in combination with another ginger species for the treatment of osteoarthritis. Although alpinia shows promise for the reduction in knee pain, more studies using alpinia alone would strengthen the evidence for this indication.
*Key to grades:
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Adults (18 years and older)
- Based on available scientific evidence, there is no proven safe or effective dosing for alpinia. A typical dose of alpinia is 2-4 grams of the herb per day or one cup of the tea, 30 minutes before meals. The tea is prepared by steeping 0.5-1 gram in 150 milliliters hot water for 10 minutes and then straining. To increase the flow of urine, 0.8 gram of Alpinia speciosa in 100 milliliters of water over seven days has been used.
Children (younger than 18 years)
- There is currently not enough scientific evidence to recommend the use of alpinia in children.
The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
- Avoid in patients with known allergy to alpinia or the ginger (Zingiberaceae) family.
Side Effects and Warnings
- Alpinia is generally considered to be well-tolerated, with few adverse effects. Alpinia has Generally Recognized as Safe (GRAS) status in the US, and is likely safe when taken by mouth in amounts commonly found in foods.
- Decreased blood pressure, pruritus (itching), abnormally slow movements or alterations in movement, diuresis, and prolonged sleep time have been reported following use of Alpinia speciosa.
- Adverse effects of taking Alpinia galanga may include decreased blood sugar levels or mild gastrointestinal complaints.
- Elevated red blood cell levels have also been noted.
- Caution is advised in patients with diabetes; in patients taking blood sugar-lowering medications; in patients with electrolyte imbalance; in patients with low blood pressure; or in patients with known allergy to the ginger (Zingiberaceae) family.
Pregnancy and Breastfeeding
- Alpinia is not recommended in pregnant or breastfeeding women due to lack of available scientific evidence.
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Interactions with Drugs
- Alpinia may increase stomach acid, and thus may decrease the effectiveness of antacids, including H2-blockers. Alpinia may also interact with proton pump inhibitor (PPIs). Caution is advised.
- Small reductions in systolic and diastolic blood pressure have been associated with the use of alpinia. Caution is advised in patients taking medications that alter blood pressure due to the risk of additive effects. Consult with a qualified healthcare professional, including a pharmacist, before taking alpinia.
- Alpinia (Alpinia speciosa) may act as a diuretic and increase urine flow. Patients taking other medications that have a similar effect should use caution as an additive effect may occur. Alpinia may decrease blood sugar levels. Caution is advised in patients with diabetes who are taking medications by mouth that alter blood sugar, or insulin. Consult with a qualified healthcare professional, including a pharmacist, before taking alpinia.
Interactions with Herbs and Dietary Supplements
- Alpinia (Alpinia speciosa) may act as a diuretic and increase urine flow. Patients taking other herbs or supplements that have a similar effect should use caution as an additive effect may occur.
- Alpinia may decrease blood sugar levels. Caution is advised in patients taking herbs and supplements that alter blood sugar. Consult with a qualified healthcare professional, including a pharmacist, before taking alpinia.
- Small reductions in systolic and diastolic blood pressure have been associated with the use of alpinia. Caution is advised in patients taking herbs and supplements that alter blood pressure due to the risk of additive effects. Consult with a qualified healthcare professional, including a pharmacist, before taking alpinia.
Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.
