Ginger has been around for thousands of years flavouring dishes and beverages of our ancestors. Besides having a zesty and spicy profile which is both complex yet energetic, ginger is not only flavourful but packs an extensive list of health benefits.
Origin of Ginger
The rhizome, main stem of ginger root is the main portion consumed. Ginger’s health benefits have been extensively documented throughout the globe. Ancient Chinese, Indian, Arabic, Sanskrit, Greek and Roman texts all speak of ginger’s medicinal powers to treat and prevent many infections and aliments.
Ginger does not grow in the wild and its true origins are not exactly known. Indians and Chinese are believed to have cultivated ginger as a tonic root some 5000 years ago. Ginger was an important and popular flavouring ingredient being traded over 2000 years ago from India to Roman Empire and rest of Europe and Asia.
By middle ages with the fall of Roman Empire and rise of Ottoman Empire, ginger continued to be imported by Arab merchants as part of the spice trade. For longer shelf life, ginger was transported in a preserved form to be used in sweet and baked goods. Queen Elizabeth I of British Empire is credited with the invention of the “gingerbread man” which became a popular Christmas treat, even today.
What is Ginger?
Ginger is a flowering plant belonging to the Zingiberaceae family, which is related to turmeric, cardamon and galangal. It is one of the most common consumed spices around the world, used by many different cultures in various dishes, beverages and condiments.
The oily resin, oleoresin, from ginger root contains hundreds of bioactive compounds and metabolites such as gingerol, shogaol, paradol and zingerone. Because majority of ginger is ingested as food, it accumulates in our gastrointestinal tract where it produces many healing and preventative effects. The anti-inflammatory properties within these compounds generate vast therapeutic benefits from relieving common colds and nausea, to improving brain cognition and reducing risk of cancers. 
Ginger is readily sold in many grocery stores and can be found in fresh, ground or capsule form (as a supplement). In addition, ginger essential oils and creams can be found within produce or cosmetic shelves.
Powerful Benefits of Ginger
Gingerol is a group of several bioactive ingredients which have been named after ginger, and for good reason. Gingerols and shogaols contain numerous anti-inflammatory and antioxidant properties and have been the focus of much scientific research regarding various medical treatments and applications.
6-gingerol is the most commonly studied compound, both in test tubes (in vitro) and in small animals or humans (in vivo) showing significant anti-inflammatory, anti-oxidation and anti-cancer properties, that fights various diseases and conditions.  6-shogaol has also been extensively studied producing similar powerful anti-inflammatory effects involving vast ranging conditions.
Treats Nausea and Morning Sickness
Ginger has an extensive documented history as a natural remedy for sea and morning sickness. Commonly, ginger is best known for treating nausea and vomiting. Recent scientific review compared 12 studies including one on 1278 pregnant women, finding ginger to be effective treatment in decreasing nausea with minimal to no side effects. 
Ginger has also been shown to relieve nausea in patients post surgery. Also, cancer patients receiving chemotherapy showed that ginger reduced the severity of nausea. [5,6,7]
Anti-Inflammatory—Reduces Muscle Soreness and Physical Fatigue
Delayed onset muscle soreness (DOMS) is a well established physiological effect occurring from moderate to extensive physical activity. Exercising muscles accumulate micro-tears and damage which results in physical tightness, soreness along with decreased mobility around focal joints. Ginger’s anti-inflammatory ingredients shown to effectively decrease DOMS, especially if consumed before exercise. 
Studies on ginger demonstrated muscle pain reduction both in upper and lower body exercises involving rotational joints such as elbows and knees.[9,10] Around 2 grams of ginger appeared to be a perfect dose leading to less pain and tightness, and better range of motion after exercise. In addition, some studies do not show immediate pain relief but rather an accumulating positive day-to-day effect with longer consumption periods (around one to two weeks). [11,12]
Anti-Inflammatory—Reduces Effects of Osteoarthritis
Osteoarthritis is also referred to as the degenerative bone disease and is the most common form of arthritis. Joints which we use more often such as hands, knees, hips and spine are typically affected. Osteoarthritis affects the cartilage between bone joints, causing friction against bone surfaces and leading to swelling, inflammation and pain. Ginger’s extract has been studied as a natural remedy regarding bone degeneration with some promising results.
One study showed ginger oil to reduce arthritis and rheumatoid arthritis in the leg joints of small animals. [13,14] In another controlled human trial, 247 participants with osteoarthritis reported reduced knee pain and required less medication after administered ginger extract. 
Tumor necrosis factor (or TNF for short) is a cell signalling protein and an important part of the immune system. TNF is body’s natural defence which coordinates immune response causing inflammation to fight off infection. When you’re sick, high TNF levels are a good sign. But when you’re not sick, high levels of TNF, specifically TNF-alpha, confuse the immune signalling and begin to attack healthy or un-infected body parts, like the joints. Some of the test tube experiments demonstrated that ginger extract is able to reduce human TNF-alpha protein, leading to less inflammation and arthritis symptoms. 
Anti-Inflammatory—Reduces Respiratory Illnesses (Asthma)
Asthma is a condition where the smooth muscle cells within the airway are hypersensitive or inflamed, leading to restriction of the area. For centuries, ginger has been used as a natural remedy to treat respiratory illnesses including asthma. Active ingredients within ginger were investigated and have been shown to reduce overall allergic response within airway smooth muscles. 
A small animal trial revealed that 6-gingerol was one of the main active compounds in lowering factors contributing to hypersensitivity and inflammation of airway smooth muscle cells associated with allergic and respiratory illnesses. 
Anti-Diabetic—Lowers Blood Sugars
High blood sugar can pose many negative effects like frequent urination, increased thirst and headaches. This is also a precursor to other significant diseases such as the metabolic syndrome, which can lead to type 2 diabetes. Ginger has been shown to reduce fasting blood sugars as well as stabilize blood sugar levels long-term, even in diabetic patients.  This showcases ginger as an effective preventative tool in decreasing the risk of high blood sugar related symptoms and diseases. The main active ingredient is again 6-gingerol, which has also been attributed to improving insulin sensitivity and overall sugar (glucose) uptake from bloodstream into cells. 
Fresh/raw ginger possesses same powerful anti-inflammatory properties as powdered or extract variants and has been tested on small diabetic animals. The results show significant decreases in all diabetic markers including lower levels of overall blood glucose, cholesterols and triacylglycerol levels; as well as lower levels of urine proteins, decreased thirst and urine production and weight loss. 
Ginger has been investigated for overall blood health and lipid management. Our modern diet comes with high quantity of fats, some of which negatively impact blood circulation. High levels of low density lipoprotein (LDL) have been attributed to number of problems including increased risk of heart disease. A study explored the effect of ginger extract on diabetic and hypothyroid animals, found a reduction in LDL, total cholesterol and overall triglyceride levels.  A human trials involving 85 people with high cholesterol showed, 3 grams of powdered ginger resulted in significant reductions in most fat types.  All ginger supplementation, in either form, showed reduction in blood triglycerides and total cholesterol.
Reduces Menstrual Pain (Dysmenorrhea)
Menstrual pain or dysmenorrhea is physical pain or discomfort felt during a women’s menstrual cycle. In today’s environment, such discomforts are usually treated with non-steroidal anti-inflammatory drugs (NSAIDS), such as ibuprofen. Some women are not fans of NSAIDS due to negative effects which may compound over time affecting cyclical onset of menstrual pain.
Due to its anti-inflammatory effects, ginger has a long history of being used as a natural remedy to alleviate such physical discomforts. Studies show that just one gram of ginger supplementation can be just as effective in relieving pain intensity and duration as some established drugs like ibuprofen during primary dysmenorrhea. [24,25,26]
Indigestion, also known as dyspepsia, is a condition where digestion is somehow impaired. The symptoms may including upper abdominal pain, abdominal fullness, heartburn, nausea, belching and may sometimes be painful. Indigestion is being attributed to the delayed emptying of the stomach.
One of the significant benefits of ginger is its ability to improve digestion and support overall health of the digestive tract. Ginger has been shown to speed up emptying of the stomach in people suffering from indigestion. The improved emptying times vary between 25 to 50 percent, but all show ginger’s ability to reduce indigestion. [27,28]
Indigestion can also be a symptom of stomach ulcers, which are inflated lining of the stomach. Ginger research has found that its anti-inflammatory compounds such as 6-gingerol and 6-shogaol reduced aspirin induced ulcer formation, by decreasing inflammatory protein levels (TNF-alpha) and their activity. 
Can Help Fight Cancer
The same powerful antioxidant compounds that produce numerous health benefits throughout the body, may also possess cancer fighting abilities. This is a fast developing research area, where effects of ginger are examined on various types of cancerous cells.
Though majority of experiments have been conducted primarily in test tubes (in vitro), the results are promising. The studies show that ginger’s components such as 6-gingerol have potential in decreasing and even blocking ovarian, pancreatic and prostate cancerous cell growth. [30,31,32]
Although every ginger variant possesses 6-gingerol, the root’s raw form contains largest amounts of this potent compound.  The antioxidant activity of 6-gingerol as well as 6-shogaol appear to effect several cellular signalling pathways, leading to decreased expansion and initiating cancer cell death (apoptosis) in oral, cervical and gastrointestinal cancers. [34,35]
Chronic inflammation has been associated to number of health problems including cognitive decline and acceleration of the aging process. Dementia and other neurodegenerative conditions such as Alzheimer’s and Parkinson’s disease have been linked to oxidative stress and chronic inflammation. Ginger posses great promise for brain’s health and wellbeing due to its numerous antioxidant and anti-inflammatory compounds.
The mechanism is still being understood but, believed to involve ginger’s antioxidant ability; protecting brain cells against free radical attacks. This has been seen in animal studies where ginger extract prevented damage and maintained brain cell integrity. [36,37] These cellular changes can result in grand scale improvement of brain activity and cognition, which was shown in a human trial study of middle-aged women. 
Ginger experiments show promise in possible treatments of dementia symptoms, including Alzheimer’s disease. [39,40]
Helps Fight Bacterial and Fungi Infections
Ginger’s properties also help to stop fungal infections from yeast infections to athlete’s foot. Studies going back almost two decades, all support ginger’s antimicrobial abilities for eliminating different fungi. Test tube studies showed ginger extract as effective remedy against fungal infections in the mouth; as it was also found to be the most effecting fungus killing agent when compared to 28 other plant extracts. [41,42]
In addition, as an effective anti-fungal agent, ginger also holds anti-bacterial abilities. Ginger extract used in test tube experiments (in vitro) has been shown as an effective treatment against drug-resistant bacteria. [43,44] Other in vitro studies, found that ginger can stop the growth of mouth bacteria that cause gum disease, gingivitis and periodontitis. 
Fresh ginger has been found to possess anti-viral activity. Human respiratory syncytial virus (HRSV) causes respiratory tract infections and is the most common cause for diseases like bronchiolitis and pneumonia. In vitro experiment using fresh ginger show effectiveness against HRSV in human respiratory tract cells. 
With current diet, we often don’t get enough important vitamins, minerals and elements. These micronutrients not only participate in benefits discussed in this article, but also take part in numerous metabolic processes which maintain body’s function and fitness levels. Another benefit of ginger is that it contains number of important micronutrients and phytonutrient, including:
- vitamin C (L-ascorbic acid)
- vitamin B1 (thiamin)
- vitamin B2 (riboflavin)
- vitamin B3 (niacin)
- vitamin B5 (pantothenic acid)
- vitamin B6 (pyridoxine)
Some if these micronutrients are in small concentrations (like calcium, zinc, riboflavin and thiamin); while other minerals (such as chromium, magnesium, zinc and potassium) are ginger’s main active nutrients. All these components play important roles in blood circulation, growth development, tissue regeneration and repair, bone density, reproductive system and overall metabolic health. For example, ginger’s potassium content is comparable to bananas—a food that is a standard for high potassium. Even though we consume small quantity of ginger, the presence of many micronutrients makes it an even more effective product.
Ginger possesses significant health benefits including reducing nausea, inflammation, muscle soreness, osteoarthritis while improving gut health and digestive tract. Ginger has also been shown to improve blood sugar levels while managing cholesterol and effective anti-fungi and anti-bacterial treatments.
Along with all extensive health benefits, ginger has been proven safe to consume in various forms, and is a big part of many cultures all over the world. Ginger’s unique and delicious flavour makes an easy and tasteful addition to almost any food or beverage, making it a true superfood.
