In this article, you'll learn all about the benefits of ginger, how it works, and the best ways to use it.
What is ginger?
Ginger is a flowering plant whose rhizome is used as a spice and medicinal herb. The root contains a variety of bioactive compounds, particularly gingerols and shogaols, which are responsible for most of its health benefits. Ginger is used both culinary and medicinally and is known for its bold, spicy flavor. In natural medicine, ginger is often used in the form of tea, capsules, powder, or as fresh root [1].
Synonyms for ginger
In addition to its scientific name, Zingiber officinale, ginger is also known as ginger root . In traditional medicine and naturopathy, it is often referred to as ginger root or simply ginger root . In many Asian cultures, ginger is considered an essential ingredient in both cooking and medicine [2].
Where does ginger come from?
Ginger originates from southern Asia, but is now cultivated in many tropical and subtropical regions worldwide. Especially in India and China, ginger has a long history of use in traditional medicine, where it is used to treat digestive problems, inflammation, and colds. Today, ginger is also increasingly valued in the Western world for its medicinal properties and is used in modern natural medicine [3].
Versatile uses of ginger
Ginger can be used fresh, dried, powdered, or as oil or juice. After harvesting the ginger roots, the rhizome is either used fresh or dried and powdered, depending on the intended use. Ginger extract is used in many dietary supplements and medications, obtained through a special extraction process to concentrate the active compounds, such as gingerol [4].
Health benefits of ginger
Ginger and digestion
One of the most well-known benefits of ginger is its ability to aid digestion. Ginger stimulates the production of digestive enzymes and promotes muscle movement in the gastrointestinal tract, helping to relieve digestive problems such as gas, nausea, and bloating. Ginger is often used to relieve travel sickness and morning sickness during pregnancy. Studies show that ginger can effectively reduce nausea, especially in pregnant women and people who suffer from travel sickness [5].
Ginger and inflammation
Ginger has powerful anti-inflammatory properties that help reduce chronic inflammation in the body. The active compounds in ginger, particularly gingerols, inhibit the production of pro-inflammatory enzymes, making it a natural remedy for inflammatory conditions like arthritis. Studies have shown that ginger can reduce inflammation and pain in people with osteoarthritis and rheumatoid arthritis [6].
Ginger and the immune system
Ginger is also known to boost the immune system. Ginger's anti-inflammatory and antioxidant properties help support the immune system by neutralizing free radicals and strengthening the body's defenses against pathogens. Ginger can help reduce the risk of infections and prevent colds and flu. Ginger tea is a popular home remedy for sore throats and coughs due to its anti-inflammatory and expectorant properties [7].
Ginger and blood sugar control
Ginger may help regulate blood sugar levels and improve insulin sensitivity. Studies have shown that ginger can lower fasting blood sugar in people with type 2 diabetes. Furthermore, ginger may help stabilize insulin levels and reduce the risk of blood sugar fluctuations. This makes ginger a useful tool for people looking to improve their blood sugar control [8].
Ginger and weight management
Ginger may also play a role in weight management, as it can boost metabolism and promote fat loss. Ginger increases thermogenesis, the process by which the body burns fat to produce heat. Studies have shown that ginger can increase satiety and reduce body weight, especially when combined with a healthy diet and regular exercise [9].
Ginger and heart disease
Ginger may also help improve heart health by lowering cholesterol levels and improving blood circulation. Studies have shown that ginger may help reduce the risk of cardiovascular disease by lowering "bad" LDL cholesterol and stabilizing blood lipids. Ginger also has a blood-thinning effect, which may reduce the risk of blood clots and stroke [10].

How does ginger work in the body?
Ginger works through its bioactive compounds, particularly gingerols and shogaols, which have anti-inflammatory, antioxidant, and carminative properties. These compounds support digestion by stimulating gastric acid production and intestinal motility. At the same time, they inhibit pro-inflammatory enzymes, reducing inflammatory responses in the body. Ginger also helps stabilize blood sugar levels and boost the immune system by neutralizing free radicals and promoting the production of anti-inflammatory molecules [11].
Recommended dosage and use of ginger
What is the recommended dosage?
The recommended dosage of ginger depends on the intended use. Doses of 1 to 1.5 grams of ginger per day are often recommended for treating digestive problems and nausea. For anti-inflammatory effects and to support heart health, doses of up to 3 grams per day can be used. Ginger can be taken as a fresh root, powder, tea, or dietary supplement. It is recommended to increase the dosage gradually to minimize potential side effects [12].
When should you take ginger?
Ginger can be taken at any time of day, either with or without food. For digestive problems or nausea, ginger can be taken shortly before meals to aid digestion. For a general anti-inflammatory effect or to boost the immune system, ginger can be taken throughout the day. Ginger tea is particularly popular and can be consumed at any time of day [13].
Side effects and safety of ginger
Is ginger safe?
Ginger is generally considered very safe and well-tolerated, even in higher doses. Serious side effects have rarely been observed in clinical studies. However, people taking blood-thinning medications should be cautious, as ginger can affect blood clotting. Pregnant women should limit their ginger intake to about 1 gram per day to avoid potential complications [14].
What are the side effects of ginger?
The most common side effects of ginger include mild stomach upset, heartburn, and a burning sensation in the mouth, especially at higher doses. In rare cases, allergic reactions such as skin rashes may occur. It is recommended to reduce the dose if these side effects occur. People taking blood thinners or suffering from gallstones should consult a doctor before taking ginger [15].
Ginger compared to other ingredients
Ginger vs. Turmeric
Ginger and turmeric are both potent anti-inflammatory spices, but they have different mechanisms of action. While ginger works primarily through its gingerols and shogaols, turmeric contains the active ingredient curcumin, which has potent anti-inflammatory and antioxidant properties. Both spices can be used together to maximize their anti-inflammatory benefits and support overall health [16].
Ginger vs. Peppermint
Both ginger and peppermint are commonly used to support digestion. Ginger promotes gastrointestinal movement and reduces nausea, while peppermint relaxes intestinal muscles and relieves cramps. Both medicinal plants can be used together to comprehensively treat digestive complaints [17].
Uses of ginger
Fresh ginger is available in most supermarkets and grocery stores and can be consumed fresh, dried, or in powder form. Fresh ginger is often used in cooking to add a spicy flavor to dishes, while dried ginger and ginger powder are more commonly used in supplements and teas. Ginger extract is a concentrated form used in many supplements to provide therapeutic doses [18].
