Ginger (Zingiber officinale Roscoe)
Ginger is a perennial herbaceous plant native to South Asia, belonging to the Zingiberaceae family, and it is best known for its aromatic rhizome: knobbly, irregular, with a thin beige skin and a fibrous, pale-yellow interior. Growing underground, the rhizome branches into twisted shapes and is characterized by an intense, penetrating fragrance that is at once citrusy, earthy, and slightly pungent. To the touch it feels firm and compact, while when sliced or grated it releases essential oils that highlight its fresh, spicy aroma.
The flavor of ginger is bold, with a lively spiciness combined with bright, lemony notes and a subtle woody background. This unique profile makes it an extremely versatile ingredient: it can be grated fresh, sliced, crushed, dried, or ground into powder. In the kitchen it is used to flavor both sweet and savory dishes, herbal teas, marinades, soups, curries, sauces, and baked goods; in desserts it adds a warm, vibrant spice, while in savory recipes it brings a warming, aromatic depth.
Within the rhizome are aromatic compounds such as gingerols and shogaols, responsible for its pungent sensation and characteristic freshness, along with essential oils, fibers, and small amounts of minerals. Ginger thrives in warm, humid climates, in loose, deep soils and with good light exposure. It is usually harvested when the leaves begin to yellow, indicating that the underground part has completed its development.
With its unmistakable fragrance, bright flavor, and ability to bridge fresh vegetal notes with warm spice, ginger has become a symbol of contemporary gastronomy, while remaining firmly rooted in ancient culinary traditions. Its presence in the kitchen brings a vibrant, refreshing yet warming touch to dishes – a small rhizome that contains surprising sensory richness.
The rhizomes are basically of two types, the white one (more commonly used and with greater health properties) and the red one.
Botanical Classification:
- Kingdom: Plantae
- Order: Zingiberales
- Family: Zingiberaceae
- Genus: Zingiber
- Species: Zingiber officinale
Plant Characteristics:
- Growth Form: Zingiber officinale is a perennial plant that typically grows 1-1.5 meters (3-5 feet) in height. It has leafy stems that arise from underground rhizomes.
- Leaves: The leaves are elongated, lanceolate, and can reach up to 20-30 cm (8-12 inches) in length. They are arranged alternately and have a distinctive ribbed texture.

Environmental and Safety Considerations:
- Environmental Impact: Ginger cultivation generally has a low environmental impact but requires a consistent supply of water and well-managed soil practices.
- Safety: Ginger is safe for most people when consumed in moderate amounts. However, excessive consumption may lead to gastrointestinal discomfort. It may interact with certain medications, so it is advisable to consult a healthcare provider before using it medicinally.
Studies
Widely used in the food and medical fields.
Among its components are interesting bio-actives: gingerol (co-responsible of spiciness), zingiberene, zingerone (co-responsible of spiciness), shogaol which has anti-inflammatory properties.
Studies
Zingerone has demonstrated particular properties, such as antioxidant, anti-inflammatory, anticancer and antidiabetic. As oxidative stress and inflammation contribute to acute and chronic myocardial lesions, this component can be a powerful treatment in the prevention and treatment of heart failure (1).
This study carried out an in-depth meta-analysis of the safety of ginger to counteract the severity of nausea and postoperative vomiting. Ginger is safe and well tolerated and can reduce the demand for antiemetic drugs (2).
Chemotherapy has serious side effects that may be detrimental to the patient, namely complaints of nausea and vomiting. To reduce the side effects of chemotherapy, many patients in our country choose herbal therapy. One such therapy is the intake of ginger. The aim of this article is to explore the effectiveness of ginger to overcome nausea and vomiting caused by chemotherapy in breast cancer patients. The method used is a systematic review. Results of the study suggest that ginger is only effective to reduce nausea, but does not lower the frequency of vomiting caused by chemotherapy in breast cancer patients (3).
It has an antifungal activity through its oil, which, used at 2% together with a 1.5% of its extract delays the ripening of the fruit Papaya (4).
Together with citric acid, it serves to improve the softness of meat in deli products (5).

Abstract. The rhizome of the Zingiber officinale Roscoe, a biennial herb growing in South Asia, is commonly known as ginger. Ginger is used in clinical disorders, such as constipation, dyspepsia, diarrhoea, nausea and vomiting and its use is also recommended by the traditional medicine for cardiopathy, high blood pressure, palpitations and as a vasodilator to improve the circulation. The decoction of ginger rhizome is widely used in Ayurvedic medicine. In this papery by high-performance liquid chromatography, we have seen that its main phytomarkers were 6-gingerol, 8-gingerol and 6-shogaol and we report the effects of the decoction of ginger rhizome on cardiovascular parameters and on vascular and intestinal smooth muscle. In our experimental models, the decoction of ginger shows weak negative inotropic and chronotropic intrinsic activities but a significant intrinsic activity on smooth muscle with a potency on ileum is greater than on aorta: EC50 = 0.66 mg/mL versus EC50 = 1.45 mg/mL.

Abstract. Ginger (Zingiber officinale) is a spice traditionally used to treat indigestion, nausea and vomiting. Ginger extracts accelerate gastric emptying and stimulate gastric antral contractions. These effects are mainly due to the presence of gingerols and shogaols and their activity on cholinergic M receptors and serotonergic 5-HT and 5-HT receptors. Various researches on this subject have led to controversial results, due to the chemical instability of ginger extracts and particularly of gingerols, which are readily-oxidizable substances. A systematic review of double-blind, placebo-controlled, randomized studies highlighted the potential efficacy of ginger on the prevention and treatment of nausea and vomiting of various origins, even though additional controlled studies are needed. This review focuses on pregnancy-induced nausea and vomiting and on chemotherapy induced nausea, and hypothesizes a therapeutic role for ginger extracts in case of side effects, as an alternative to traditional prokinetic drugs such as domperidone, levosulpiride or metoclopramide.

Antifungal and antimycotoxigenic effects of Zingiber officinale, Cinnamomum zeylanicum and Cymbopogon martinii essential oils against Fusarium verticillioides. Food Addit Contam Part A Chem Anal Control Expo Risk Assess. 2020 Sep;37(9):1531-1541. doi: 10.1080/19440049.2020.1778183.
Abstract. There is an increasing demand for fungi control in grains, especially toxigenic. Also, there is growing concern on the use of synthetic fungicides; thus alternatives are needed. The aim of this study was to evaluate the antifungal and antimycotoxigenic action of essential oils (EOs) from Zingiber officinale, Cinnamomum zeylanicum and Cymbopogon martinii against Fusarium verticillioides, a spoilage and toxigenic fungus. Essential oils were first chemically characterised by gas chromatography coupled to mass spectrometry, and their antioxidant potential was measured by the DPPH, ABTS and FRAP methods. Minimum inhibitory concentration (MIC) and disc diffusion were used to assess antifungal activity. Scanning electron microscopy was used to evaluate morphological changes in the fungus. Antimycotoxigenic activity of the EOs against the production of fumonisin B1 and B2 by F. verticillioides was evaluated using ultra-high-performance liquid chromatography system. Z. officinale, C. zeylanicum and C. martinii EOs were predominantly composed by zingiberene and geranial; eugenol; and geraniol, respectively. All the EOs had high antioxidant power, especially that from C. zeylanicum. The MICs were 250, 500 and 2,000 µg mL-1 for C. zeylanicum, C. martinii and Z. officinale EOs, respectively. Mycelial reduction of F. verticillioides was observed when EOs were used, and the lowest activity was detected in the Z. officinale EO. Overall, the tested EOs promoted structural damage to the fungal cell wall, decreased conidia size and mycelial reduction. Antimycotoxigenic evaluation of the EOs evidenced a significant reduction (p < .05) in the production of fumonisins B1 and B2 with all the EOs evaluated in the study. These results suggest that especially C. zeylanicum and C. martinii EOs are highly useful for controlling F. verticillioides and fumonisins production.

Effect of Ginger Supplementation on Proinflammatory Cytokines in Older Patients with Osteoarthritis: Outcomes of a Randomized Controlled Clinical Trial. J Nutr Gerontol Geriatr. 2016 Jul-Sep;35(3):209-18. doi: 10.1080/21551197.2016.1206762.
Abstract. There is limited evidence that ginger powder consumption can relieve pain and inflammation due to specific anti-inflammatory phytochemical constitutents. This study investigates the effect of ginger supplementation on proinflammatory factors in participants (n = 120) of a randomized double-blind placebo-controlled 3-month clinical trial investigating knee osteoarthritis. Patients were randomly assigned to one of two groups: the ginger group (GG) or the placebo group (PG). Administered daily for 3 months, participants in the GG intervention received capsules containing 500 mg of ginger powder, while PG participants received capsules filled with 500 mg starch. Serum samples collected at baseline and 3 months were analyzed for serum levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). At baseline, proinflammatory cytokine concentrations did not differ by group. However, at 3 months, both cytokines decreased in the GG relative to the PG. The results of this study indicate that ginger supplementation may have a promising benefits for knee osteoarthritis and may, therefore, may warrant further study.
