Herb's Introduction
Pilea microphylla, commonly known as the Gunpowder Plant or Artillery Plant, is a fascinating and versatile herb belonging to the nettle family, Urticaceae. Despite its relation to the stinging nettle, this particular species is a non-stinging, slender, and succulent herb. It is widely recognized for its delicate, fern-like appearance and its unique method of pollen dispersal, which gives it its explosive common names. The plant is a fast-growing annual or perennial, often forming dense mats of vibrant green foliage. While it is native to tropical and subtropical regions of the Americas, its ease of cultivation and hardiness have allowed it to become a popular ornamental houseplant and a naturalized species in many parts of the world. Beyond its decorative appeal, Pilea microphylla holds a long and rich history in traditional medicine across various cultures, where it is valued for its broad spectrum of healing properties.
Name in Different Countries
The common names for Pilea microphylla often allude to its peculiar botanical characteristics or its appearance. Its primary common names in English are Gunpowder Plant and Artillery Plant, both of which are direct references to the dramatic way it ejects its pollen. It is also sometimes called Rockweed, due to its habit of growing in rock crevices and on walls, or Friendship Plant, because of its popularity as a shared houseplant. In other parts of the world, it is known by names that reflect its local use or appearance: Marathi: rip Chinese: 小叶冷水麻 (xiǎo yè lěng shuǐ má), which translates to "small-leaved cold water hemp," referencing its family and leaf size. Finnish: Sammalpiilea (Moss Pilea) French: Pilée à petites feuilles (Pilea with small leaves) German: Kleinblättrige Kanonierblume (Small-leaved Cannoneer Flower) Spanish: espumilla (little foam), possibly referring to the frothy appearance of the pollen bursts. Swedish: Mosspilea (Moss Pilea) Jamaican: In Jamaica and the Caribbean, it is often simply referred to as Artillery Plant.
Terminology
To fully understand Pilea microphylla, it is helpful to break down some of the botanical and medical terminology associated with it. Synonyms: The long list of synonyms provided (e.g., Adicea microphylla, Urtica microphylla) indicates that the plant has been classified and reclassified multiple times by different botanists throughout history. Synonyms are alternative scientific names for the same species, and they often reflect changes in taxonomic understanding or regional differences in naming conventions. Family (Urticaceae): This is the nettle family. While many members, like the common stinging nettle, are known for their stinging hairs, Pilea microphylla is a non-stinging relative. Slender succulent herbs: This describes the plant's physical structure. "Slender" means it has a delicate, thin stem and branches, while "succulent" indicates that its tissues are adapted to store water, giving the leaves and stems a fleshy, plump quality. Bifarious: The leaves are arranged in two rows, one on each side of the stem, creating a flat, layered appearance. Raphides: These are needle-like crystals of calcium oxalate found in the plant's tissues. While they are a key feature, they do not cause a stinging sensation in this particular species. Monoecious: This term describes a plant species that has both male and female flowers on the same individual plant. Umbelled clusters: The flowers are arranged in small, umbrella-shaped clusters. Tepals: The outer parts of the flower, which are not clearly differentiated into petals and sepals. Achene: This is the dry, one-seeded fruit of the plant. Diuretic: A substance that increases the production of urine, helping the body to excrete excess water and salts. Anthelmintic: A substance that is used to destroy or expel parasitic worms from the body. Antioxidant: A substance that inhibits oxidation, a process that can produce free radicals and damage cells. Radioprotective: A substance that provides protection against the harmful effects of radiation.
Availability
Pilea microphylla is a widely distributed plant, a testament to its hardiness and adaptability. Its native range spans the subtropical and tropical regions of the Americas, including Florida, Mexico, Central America, the Caribbean, and parts of South America. However, due to its common use as an ornamental plant, it has become naturalized in many other tropical and subtropical areas around the globe, including parts of Asia, Africa, and Australia. As a result, it is readily available. It can be found growing in gardens, in the wild as a ground cover, in rocky areas, on walls, and in moist, shaded environments. It is also a very common and popular houseplant, sold in nurseries, garden centers, and online, making it easily accessible for home cultivation. While it may not be a staple in commercial herbal markets, its prevalence in natural environments and home gardens means that it can be easily procured for traditional use in the regions where it grows.
External Look
The external appearance of Pilea microphylla is a key part of its appeal and identification. It is a slender, low-growing, succulent herb, typically reaching heights of up to 12 inches (30 cm). The stems are delicate and have a somewhat transparent quality. The leaves are the plant's most notable feature, appearing in dense, bifarious arrangements along the stems, giving the plant a flat, fern-like or moss-like texture. They are incredibly small, measuring only up to 4 mm by 3 mm, and are ovate-orbicular in shape with a smooth, bright green, and somewhat glossy surface. When the plant blooms, its unique character becomes apparent. The tiny, monoecious flowers are arranged in small, umbellate clusters. The male flowers, when mature and exposed to water (such as from a sprinkle or a rain droplet), burst open with a sudden force, ejecting a small cloud of pollen into the air. This rapid, smoke-like expulsion of pollen is what gives the plant its common name, Gunpowder Plant, as it resembles a tiny artillery cannon firing. This dramatic display is a remarkable botanical spectacle, and it distinguishes Pilea microphylla from its relatives.
Healing Properties
Pilea microphylla is a revered plant in various traditional medicine systems, valued for a wide array of healing properties that address both internal and external ailments. The plant is considered to be: Diuretic and Liver Support: It is widely used to promote urination, which can help in cases of edema, urinary tract infections, and liver or urinary inflammation. Its use in treating hepatitis points to its potential for supporting liver health. Digestive and Anthelmintic: The plant is traditionally employed to treat various gastric and intestinal troubles, including diarrhea. Its anthelmintic property suggests its use in expelling parasitic worms. Anti-inflammatory and Analgesic: A paste made from the whole plant or its leaves is applied externally to reduce swelling and pain associated with rheumatic joints, skin diseases, sores, and bruises. Its anti-inflammatory properties are also noted for treating internal inflammation. Antioxidant and Radioprotective: Modern ethnomedicinal studies highlight its antioxidant and radioprotective qualities. These properties are crucial in protecting the body's cells from damage caused by free radicals and radiation, which could have implications for long-term health and disease prevention. Respiratory and Circulatory Support: In some regions, like Jamaica, it is used for relief in cases of asthma and other lung diseases. In Taiwan, it is documented for its ability to lower blood pressure and is even used in cases of stroke and brain hemorrhage, suggesting a positive effect on the cardiovascular system. Women's and Children's Health: In some cultures, it is considered a womb cleanser. It is also used to make a tea for women in labor and for both mother and child after birth.

This method allows the plant's anti-inflammatory and antiseptic compounds to be absorbed directly into the skin. For Internal Use: Tea: For internal issues such as gastric troubles, liver inflammation, or respiratory ailments, the plant is brewed into a tea. To prepare the tea, a handful of fresh leaves and stems are steeped in hot water. The concentration can be adjusted based on traditional recipes and personal preference. The tea is then strained and consumed. In Jamaica, it is traditionally brewed with 'egg trash' (egg shells) for women in labor and after childbirth. It is crucial to note that while this plant is widely used in traditional medicine, it is always recommended to consult with a healthcare professional before using any herbal remedy, especially for serious conditions.
