Enxtra Alpinia Galanga Root Extract
Also known as: Galangal, Greater Galangal, Siamese Ginger, *Alpinia galanga*
Overview
*Alpinia galanga*, commonly known as Galangal, is a perennial herb native to Southeast Asia, particularly Indonesia and Thailand. It belongs to the Zingiberaceae family and is revered both as a culinary spice and a traditional medicinal herb. The plant is known for its phytochemical richness, including terpenes, phenolics, and alkaloids, contributing to its therapeutic properties. Traditionally, it has been employed to address a variety of health ailments such as digestive disorders, cardiovascular issues, rheumatism, and inflammation. While its traditional use is extensive, scientific studies mainly consist of in vitro and animal research, with some clinical trials showing potential health benefits. Nevertheless, further research is essential to validate its therapeutic efficacy and safety for widespread use.
Benefits
1. **Mental Alertness and Cognitive Function**: A double-blind, placebo-controlled trial demonstrated that *Alpinia galanga* extract improved alertness and reduced fatigue in healthy adults (p < 0.05). The effect was sustained up to 5 hours after dosing. 2. **Antidiabetic Activity**: Studies in diabetic rats revealed that the extract decreased blood glucose by up to 64.8% and positively influenced lipid profiles at doses of 200-400 mg/kg body weight (p < 0.01). 3. **Pain Relief**: Though effects are modest, a systematic review indicated that Zingiberaceae extracts, including galangal, showed significant pain relief compared to placebo (p = 0.004). 4. **Antimicrobial Activity**: The extract demonstrated inhibitory effects against key bacteria such as *Staphylococcus aureus* and *Helicobacter pylori*, indicating its potential uses in combating infections. The evidence primarily supports benefits in healthy adults and those with metabolic conditions.
How it works
*Alpinia galanga* exerts its effects through various bioactive compounds. Its terpenes, phenolics, and alkaloids modulate physiological responses by interacting with biological membranes and proteins. For instance, the inhibition of the enzyme α-glucosidase contributes to its antidiabetic properties, while the extract's antimicrobial effects stem from the inhibition of IL-8 secretion and the suppression of pathogenic bacterial growth, affecting multiple biological pathways related to inflammation and metabolism.
Side effects
Current understanding of *Alpinia galanga*'s safety profile suggests minimal adverse effects at therapeutic doses. Acute toxicity studies indicate no mortality even at high doses (up to 1600 mg/kg), although some cell damage was observed. Common side effects have not been well-documented in humans but animal studies suggest a low incidence of adverse reactions. Rare side effects have not been reported. Caution is advised for pregnant or breastfeeding women due to limited safety data. Furthermore, patients with diabetes should closely monitor their condition, given the extract's hypoglycemic properties. While no significant drug interactions are known, it is prudent to consult healthcare professionals prior to use.
Dosage
Clinical studies suggest a minimum effective dose of 300 mg of *Alpinia galanga* extract for cognitive benefits. For potential antidiabetic effects, animal studies utilized doses of 200-400 mg/kg. Human studies have also indicated an optimal dosage around 300 mg per day for cognitive enhancement. Acute toxicity studies in rats found safety thresholds up to 1600 mg/kg. The extract is generally taken in capsule form, with administration once daily, 30 minutes after lunch being the most common method observed in studies.
