What are the morphological characteristics of this plant?
Equisetum arvense has a perennial rhizomatous root system that produces distinct, non-branching, jointed green stems reaching up to 20 centimeters in height and sterile, scale-like leaves arranged in whorls at each node. The plant features two separate types of shoots: sterile vegetative stems used for photosynthesis and fertile reproductive stems that emerge in early spring. These fertile stems are brownish, unbranched, and terminate in a cone-like structure called a strobilus for spore production. The vegetative stems are characterized by deep longitudinal grooves and fine, hair-like branches that emerge from the nodes. Silica deposits within the stem walls provide a rough, abrasive texture to the surface.
What is the geographical distribution of this plant?
This plant is widely distributed across the temperate regions of the Northern Hemisphere, including much of Europe, Asia, and North America. It thrives in various habitats ranging from moist meadows and riverbanks to disturbed soil in gardens and roadsides. In North America, its range extends from the subarctic regions of Canada down through most of the contiguous United States. The species is particularly common in areas with high moisture levels where its rhizomes can spread easily through damp ground. It is frequently found in both wild ecosystems and anthropogenic environments like agricultural fields.
How is this plant cultivated?
This plant, commonly known as field horsetail, is cultivated in moist, acidic, and nutrient-rich soils that are kept consistently damp to support its rhizomatous growth.
Because it spreads aggressively through an extensive underground network, it is best grown in contained vessels or dedicated garden beds to prevent it from overtaking other species. It thrives in full sun to partial shade environments where it can access ample moisture without becoming completely waterlogged. Maintenance involves regular monitoring to manage its spreading tendencies and ensuring the soil remains cool and humid.
This species is primarily grown for its medicinal properties or as a natural silica source in specialized horticultural settings.
What parts of this plant are used medicinally?
This plant Equisetum arvense utilizes its aerial shoot and stem as the primary parts for medicinal applications. These structural elements are rich in silica, which makes them useful for strengthening hair, skin, and nails. Practitioners often prepare decoctions from the stems to treat urinary tract issues or to reduce edema. The high mineral content found throughout the shoot also supports bone health and tissue repair. Because the stem contains most of the plant's active compounds, it is the most frequently harvested component in herbal medicine.
According to a study published by "Environmental science and pollution research international", the shoot of Equisetum arvense L. showed the highest accumulation of copper with a value of 37.1 mg kg-1. This accumulation level is above the permissible value of 10 mg kg-1 set by the WHO. Critical attention is required in the medicinal application of herbaceous plants in treating human ailments due to their copper accumulation potentials being above the threshold. This study suggests that spontaneous surveys can provide caution regarding consumable products and bioactive compounds.

What traditional systems uses this plant?
This plant, known as field horsetail, was used in Native American herbal medicine to treat various ailments including urinary tract infections and skin inflammations. Historically, many indigenous groups utilized decoctions made from the stems to act as a diuretic or to cleanse the body. Some tribes also applied poultices made from the plant to soothe external wounds or skin irritations. Beyond indigenous practices, traditional European herbalism often employed the plant for its high mineral content to support bone health. These diverse historical applications highlight the plant's long-standing role in various cultural medicinal traditions.
According to a study published by "Sexually transmitted diseases", Equisetum arvense was one of 14 Canadian plants used in traditional First Nations' medicine. Ethanolic extracts of this botanical were tested against a panel of 28 Neisseria gonorrhoeae isolates. The study found that Equisetum arvense had weak or no antimicrobial activity against the isolates. The minimum inhibitory concentrations for this plant were recorded as being ≥256 μg/mL.

What are the pharmacological activities of Equisetum arvense?
This plant has anti-inflammatory, diuretic, antimicrobial, antioxidant, and hemostatic pharmacological activities that make it valuable in traditional medicine. Its potent diuretic properties help increase urine production to assist in fluid regulation and detoxification. The presence of antioxidant compounds protects cells from oxidative stress and damage caused by free radicals. Additionally, the plant exhibits antimicrobial effects that can inhibit the growth of various pathogenic microorganisms. Its hemostatic capabilities further allow it to assist in controlling bleeding by promoting blood coagulation.
According to a study published by "Scientific reports", Equisetum arvense L. hydroalcoholic extract (HAEA) demonstrates therapeutic potential in a rat model of ulcerative colitis involving 81 male Sprague Dawley rats. After 7 days, HAEA was shown to significantly decrease malondialdehyde (MDA), interleukin-1β (IL-1β) concentrations, and myeloperoxidase (MPO) activity while increasing superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities. Specifically, the HAEA gel 10% rectal enema was significantly effective in decreasing MDA and IL-1β and increasing GPx and SOD activities compared to positive control groups (P < 0.05). Stereoological evaluations showed that HAEA 600 mg/kg orally and the 10% gel rectal enema-treated groups had significantly higher epithelium, submucosa, and muscularis mucosa volume density compared to negative control groups (P < 0.001). These findings indicate that Equisetum arvense L. has potential as an additive therapeutic strategy in ulcerative colitis patients.
The primary pharmacological activities of this plant are shown in the list below.
- diuretic
- anti-inflammatory
- antioxidant

What medicinal compounds this plant contains?
This plant contains silica, caffeic acid, flavonoids, isoquercitrin, and kaempferol. The high concentration of silica provides significant benefits for bone and tissue health. Various flavonoids act as potent antioxidants to protect cells from oxidative stress. Within this group, isoquercitrin and kaempferol contribute to the plant's overall anti-inflammatory properties. These diverse chemical constituents make Equisetum arvense a valuable resource in herbal medicine.
According to a study published by "Planta medica", Equisetum arvense is the plant with the highest concentration of silica and is used for the treatment of inflammatory diseases. The medicinal properties of Equisetum arvense are mediated by both silica and the component identified as isoquercitrin. Analytical profiling by HPLC-UV-MS revealed that isoquercitrin exists at relevant immunosuppressive concentrations. Horsetail preparations suppress the activation and proliferation of lymphocytes through an interleukin-2-dependent mechanism. The effect of these preparations increased with the silica concentration in the decoctions. The bioactivity also influenced lymphocytes' polyfunctionality through a downregulation of IFN-gamma.
