What is Black Ginger?
Black ginger is a food ingredient that is known for its powerful nutrition components and health benefits.
Black ginger is also known as:
- Black Turmeric
- Krachai Dum
- Thai Black Ginger
- Thai Ginseng
The botanical name for black ginger is Kaempferia parviflora.
Black ginger is indigenous to Thailand. It is a member of the Zingiberaceae or Ginger food family.
Other foods in the ginger food family include cardamom, common ginger, galangal, and turmeric.
The Kaempferia parviflora (KP) rhizome has been used in Thai traditional medicine for more than one thousand years. Black ginger is being studied for allergies, diabetes, diarrhea, impotence, and more.
Compared to traditional ginger, the flesh of black ginger is darker in color. The two gingers look the same on the outside, but black ginger boasts a deep purple color on the inside.
What is Black Ginger Extract?
The dried rhizome of the black ginger plant is traditionally crushed and put into tea bags. The fresh rhizome has also been used in wine brewing. The wine is made into a tonic and is regarded as an aphrodisiac.
Black ginger supplements are also prepared with honey and made into medicinal liquors, pills, capsules, and tablets. Black ginger extract can be purchased in powdered form, a liquid form, and encapsulated. Powdered Black Ginger is sold as a food ingredient.
Black Ginger Extract is sometimes referred to as Kaempferia parviflora extract or KPE. It contains polymethoxyflavones (PMFs) and is rich in amino acids, antioxidants, selenium, tannins, anthocyanins, and flavonoids.
Black Ginger Supplements
Black ginger extract is more readily available as a dietary supplement than as a food ingredient.
Though traditional ginger supplements are more widely available, you can order black ginger extract on Amazon or directly from an online supplement store.
Black Ginger Benefits
Black Ginger has traditionally been used for many conditions and is being studied to identify additional uses.
The studies discussed below do not provide conclusive recommendations on how to use black ginger extract.
In herbal medicine, adaptogens are substances that help the body adapt to stress.
Black ginger extract has been studied for its adaptogenic properties. A study using mice found that black ginger had a similar effect as ginseng root powder. The study did not provide recommendations for human use.
Black ginger is used in Thai traditional medicine to treat asthma.
In a 2008 study, methoxyflavone derivatives from the plant were found to have anti-allergic activity.
A 2007 study also supported the use of black ginger in the treatment of allergies and related conditions.
Kaempferia parviflora has been shown to have high antioxidant activity.
Researchers believe this plant may be a source of natural oxidants. Antioxidants scavenge for free radicals and may reduce oxidative stress related to diabetes or other conditions.
An in vitro study has shown that specific polymethoxyflavones from Kaempferia parviflora have anti-inflammatory effects on cells.
Another cellular study indicated that KP suppressed inflammation at the genetic expression level and at protein production. This study was focused on inflammation related to psoriasis.
While other studies indicate that black ginger has anti-inflammatory properties, it is important to note that these studies were done on cells (in vitro) and not on human subjects.
Anti-Microbial and Anti-Inflammatory
Acne is caused by bacteria strains, including Propionibacterium acnes and Staphylococcus aureus. A 2018 study showed that KPE inhibited the growth of skin bacteria and reduced inflammation.
In 2019, researchers studied KPE as a potential treatment for Plasmodium and Toxoplasma infections. This in vitro study showed that the black ginger extract had an effect on these parasitic organisms.
Arthritis & Chronic Pain
The study found that black ginger extract reduced the pain threshold and reduced severity of osteoarthritic cartilage lesions. They also found that methoxyflavones reduced the enzymes that degrade collagen within cartilage.
Recent reports have indicated that Kaempferia parviflora has anti-cancer effects.
In 2018 researchers studied the effects of Kaempferia parviflora extract on aggressive cervical cancer cells. The study found that KPE was cytotoxic at higher concentrations. KPE use was also associated with decreased cell proliferation, migration, and invasion.
This is consistent with a 2017 study in which KPE was found to suppress the migration of cervical cancer cells.
A 2021 study indicated that Kaempferia parviflora exhibited anti-cancer activity against pancreatic cancer cells. In this in vitro study, KPE inhibited cancer cell colony formation. It also demonstrated cytotoxic activity towards cancer cells.
KPE is being studied on other cancer cells as well and it is being considered for future studies as a cancer treatment. No recent human studies on cancer and black ginger were identified.
Kaempferia parviflora extract (KPE) has been studied in rats and was found to protect the stomach lining.
Black Ginger Extract may be beneficial for heart health as well.
In addition to being used in Thai traditional medicine for the treatment of hypertension and as a diuretic, it is being studied to understand its effects on other aspects of heart health.
A 2014 study on middle aged rats showed that KPE improved vascular function, decreased subcutaneous and visceral fat, fasting blood sugar, triglyceride level, and fat storage in the liver. There were no negative effects observed in total blood count, kidney function, or liver function.
Other research indicates KPE may be beneficial in treating heart disease due to its effectiveness as a vasodilator and as an antioxidant.
If you are an athlete or interested in fitness, black ginger extract might be interesting to you.
In a 2016 study on black ginger, Kaempferia parviflora extract (KPE) was administered orally to 15 male mice for one month. Physical performance efficacy, muscle endurance, and grip strength increased in these mice.
The study explained that KPE contains polymethoxyflavones (PMFs) that activate a significant contributor to cell metabolism called AMP-activated protein kinase (AMPK).
AMPK may also enhance fat metabolism, muscle endurance, and physical performance.
Also, in a 12-week randomized control study on young athletes, KPE capsules were given daily. The test group showed significant improvements in right-hand grip strength compared to the placebo-controlled group.
It may also help to improve fitness in the elderly.
Mental and Emotional Wellbeing
In addition to influencing physical health, the methoxyflavones in black ginger may also support choline and acetylcholine in the brain. This is thought to promote mental and emotional wellbeing.
Further, it may improve neurological health, learning and memory.
Metabolism, Energy Expenditure and Weight Management
Imagine burning more calories after taking a single dose of KPE.
These results are similar to the findings of a 2014 study on KPE’s effect on brown adipose tissue in mice.
Studies like these show black gingers’ potential benefit for weight loss and weight management.
Black ginger is a famous Thai product and has been used since ancient times for erectile dysfunction. It has also been used to boost libido in both men and women.
Black ginger has been called a natural Viagra and is used as a natural PDE inhibitor to address erectile dysfunction.
Additionally, KPE promotes the production of nitric oxide (NO) which promotes vascular function. Nitric oxide (NO) plays an important role as a neurotransmitter and supports blood flow, and muscle function needed for erections.
In a 2018 study, Kaempferia parviflora ethanol extract was given to 14 older adult men with erectile dysfunction for 30 days. In a self-reported questionnaire, 13 of the men reported results that proved statistically significant in erectile function improvements and increased sex satisfaction.
This is consistent with a 2012 study that indicated KPE improved erections in healthy elderly men. Notably, testosterone levels were unchanged in this study.
