What’s Kaempferia parviflora Extract?
Kaempferia parviflora, the Thai black ginger, Thai ginseng or krachaidum, is an herbaceous plant in the family Zingiberaceae, native to Thailand. Kaempferia parviflora has been the subject of increased scientific interest in recent years.
5,7-Dimethoxyflavone (5,7-DMF), 5,7,4’-trimethoxyflavone, 5,7,3’4’-tetramethoxyflavone, the major components of Kaempferia parviflora, have anti-obesity, anti-inflammatory, and antineoplastic effects.
Health Benefits of Kaempferia parviflora Extract
1. Male Vascular Sexual Support
Also known as Thai Black Ginger, Kaempferia parviflora is native to Southeast Asia. It's been used to promote male sexual health for years, but only now has been studied in the west. And the results are impressive: two clinical studies show promise for male sexual function, response, performance, and satisfaction with results seen after 30 days.
Kaempferia parviflora works by promoting nitric oxide synthesis, which relaxes blood vessels and enables healthy blood flow, the key to healthy male sexual response. It also encourages a healthy brain response to sexual stimuli and helps to inhibit an enzyme that can affect male sexual response. And it does both of these things independently of hormone levels.
2. Clinical Effects of Kaempferia parviflora on Physical or Exercise Performance
To determine the effects of Kaempferia parviflora on physical or exercise performance, many tests were used, including maximum power output, mean power output, time to exhaustion, rating of perceived exertion, percentage fatigue, heart rate, lactate threshold, hand grip strength, 6-minute walk test, and so on. The main findings from 2 studies indicated that Kaempferia parviflora showed no acute improvement in either repeated sprint performance or endurance exercise. However, 2 studies provided data of hand grip strength test, which determined the upper-body muscle strength by using a digital dynamometer. We pooled such data based on this outcome and found that they were combinable without heterogeneity (I 2 ¼ 0%, P > .05). We found that the Kaempferia parviflora group significantly increased hand grip strength of both right-hand (standardized mean difference ¼ 0.44, 95% confidence interval ¼ 0.02-0.86, P ¼ .038) and left-hand sides (standardized mean difference ¼ 0.49, 95% confidence interval ¼ 0.07- 0.91, P ¼ .048) at 2 months compared with the placebo group.
3. Clinical Effects of Kaempferia parviflora on Pain Indicators
Clinical Effects of Kaempferia parviflora on Pain Indicators A study by Chalee compared Kaempferia parviflora cream with analgesic cream on pain reduction indicators. Pain severity, circumference of knee joint, range of motion of knee joint, and modified Western Ontario and McMaster Universities Arthritis Index score were assessed and compared within the group from baseline, or between the groups with analgesic cream. Comparing with baseline, the results in both groups showed significantly reduce pain in all indicators at 4 weeks. On the contrary, comparing with analgesic cream, Kaempferia parviflora cream showed nonsignificant different.
