This is comparable to the 1.2g daily dosage that the Thai Traditional Medicine Institute recommends, and the 1.35g utilised in the one human research on the subject (which failed to identify any acute effect).
Lower dosages have been shown to have general health protective benefits, but there isn't enough data to recommend an ideal dose.
Black ginger, also referred to as Kaempferia parviflora (Zingiberaceae family), "Thai ginseng," "Thai black ginger," or simply "Krachaidum," is a variety of Thai ginger with deep purple-coloured rhizomes (roots) that has been used in Thailand for more than a thousand years as both a food and a folk remedy.
Tropical regions like Malaysia, Sumatra, Borneo Island and Thailand are home to Kaempferia parviflora. Kaempferia parviflora is popularly thought to lengthen hill hiking, increase physical labour capacity, and decrease perceived effort among the Hmong hill people.
While the fresh Kaempferia parviflora root is used to make wine, the dried root is often ground and used to make tea bags.
In Thailand, the wine-based concoction is becoming more popular as a tonic and aphrodisiac.
Supplemental black ginger has been created in a variety of forms, including pills (powdered Kaempferia parviflora root with honey), capsules, and tablets.
Traditional Thai medicine has traditionally employed black ginger, or Kaempferia parviflora, to treat a variety of conditions, including allergies, anti-depressant, 1asthma, tiredness, weakness, impotence, gout, colic problem, diarrhoea, dysentery, peptic ulcer 5, and lowering blood sugar in diabetics. It is also utilised as a nerve tonic and a chemical that promotes lifespan.
The biological activities of black ginger extract (Kaempferia parviflora extract), which was previously reported to have antioxidant activity, cardioprotective, aphrodisiac, anticholinesterase, anti-inflammatory, anti-obesity and antimutagenic, neuroprotective, and cognitive-enhancing properties, have been demonstrated in a large number of recent studies.
Clinical investigations have shown that kaempferia parviflora extract enhances physical fitness performance.
Extract from Kaempferia parviflora has been shown to have antimalarial, antiviral, antimycobacterial, and antibacterial anti-gastric ulcer properties due to its anti-oxidative activity.
Hela human cervical cancer cells and SKOV3 ovarian cancer cells have both shown anticancer activity in response to kaempferia parviflora extract.
Kaempferia parviflora benefits
Despite demonstrating good results, a systematic evaluation of Kaempferia parviflora's therapeutic effects is ambiguous since it only included small trials.
Modern research methods have shown that Kaempferia parviflora can prevent pathological changes brought on by insulin resistance, fatty liver, and hypertension as well as suppress body weight gain and lipid accumulation.
The imbalance between energy intake and expenditure may contribute to weight gain. Brown adipose tissue is essential for regulating the body's total energy expenditure and level of body fat.
By attracting brown adipose tissue in Japanese male volunteers between the ages of 21 and 29, the ethanol extract of Kaempferia parviflora at a dose of 100 mg significantly raises whole-body energy expenditure 33.
Kaempferia parviflora is said to increase physical labour capacity and decrease perceived effort by the Mong hill tribe in Thailand.
It has been shown that taking Kaempferia parviflora extract for 8 weeks at doses of 25 mg or 90 mg increases physical fitness performance in the 6-minute walk test and 30-second chair stand test.
It also increases the expression of the scavenger enzymes glutathione peroxidase (GSH-Px), catalase (CAT), and superoxide dismutase (SOD), which reduces malondialdehyde production.
The oral administration of the sports nutritional supplement Fitnox at a single dose of 250 mg has been shown in a double-blind, placebo-controlled clinical trial to significantly increase the levels of nitrate (NO3-) and nitrite (NO2-) in serum and saliva, improving overall performance and physical endurance.
The enhancement of grip and leg strength, balance, endurance, and locomotor activity are all signs of improved physical fitness, which has been consistently observed with Kaempferia parviflora extract.
The post-physical fitness test VAS fatigue score, the chronic fatigue syndrome score, and the daily visual analogue scale (VAS) figure score are also found to be significantly higher than those in the placebo group.
However, it has been proven through repeated sprint exercise and submaximal exercise to exhaustion in college males in Thailand that acute administration of Kaempferia parviflora does not improve exercise performance, as compared with the placebo.
Conversely, it was discovered that supplementing soccer players with Kaempferia parviflora extract at 180 mg per day for 12 weeks increased their left-hand grip and right-hand grip strength compared to those in the placebo group.
However, the tests for back and leg strength, 40-yard technical ability, sit-and-reach ability, 50-meter sprint ability, and cardiorespiratory fitness did not reveal any appreciable differences from those in the placebo group 38.
Blood fluidity and blood circulation go hand in hand. The activation of fibrinolysis by a 70% methanol extract of Kaempferia parviflora has been shown to significantly increase 2blood fluidity, as shown by an extension of the euglobulin lysis time in disseminated intravascular coagulation (DIC) rat models and the fibrinolysis assays in vitro.
Methoxyflavones from Kaempferia parviflora have been linked to fibrinolysis activation. The saline extract of Kaempferia parviflora at high doses of 100 mg/kg and 50 mg/kg is found to increase the defibrillation threshold and the upper limit of vulnerability in the ventricular fibrillation (VF) of the swine heart model.
However, the threshold for ventricular fibrillation remains unchanged. Additionally, taking Kaempferia parviflora lowers both systolic and diastolic blood pressure.
On the other hand, it has been shown that the extract of Kaempferia parviflora (100 mg/kg) decreases cardiac functions in healthy rat hearts by increasing cyclic guanosine monophosphate (cGMP) levels, nitric oxide (NO) signalling, and upregulating Ca2+ transient.
This is consistent with enhanced K+ efflux and reduced Ca2+ influx caused by 5,7-dimethoxyflavone-induced vasorelaxation.
Men's sexual activity is said to be benefited by Kaempferia parviflora. However, the weights of the reproductive organs are unaffected by the ethanol extract of Kaempferia parviflora at a dosage of 70 mg/kg, but mount latency, ejaculation latency, and post-ejaculation latency are all reduced.
On the other side, a dose-dependent increase in testis blood flow has been seen using the ethanol extract of Kaempferia parviflora. Inhibition of phosphodiesterase type 5 (PDE-5) has emerged as the preferred method of treating erectile dysfunction.
But for PDE-5 inhibitors to activate cGMP-NO and cause an erection, sexual excitement is necessary. As a result, targeting the corpus cavernosum for relaxation may be a novel and successful strategy for treating erectile dysfunction.
A relaxing effect of pentamethoxyflavone on an isolated human cavernosum that has been precontrated by phenylephrine has been shown. The pentamethoxyflavone may block the L-type Ca2+ channel and cause the immobilisation of Ca2+ from the sarcoplasmic reticulum as the potential mechanism.
However, pentamethoxyflavone very slightly stimulates NO release; it does not operate as a calcium-activated potassium channels (KCa channels) opener, a PDE inhibitor, or a Rho-kinase inhibitor.
It has been shown that kaempferia parviflora extract may be used to treat erectile dysfunction caused by getting older.
Kaempferia parviflora extract significantly raises all parameters at a dose of 90 mg per day. The levels of testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone are unaffected.
You've probably never heard of Black Ginger, a superfood, but you should keep an eye on this new supplement. Yes, it has something to do with the ginger that you use to flavour Asian foods.
It is also related to turmeric, whose potent curcumin ingredient is being studied for its potential to extend life, relieve pain, and support chemotherapy and radiation treatment.
