The dried leaves and flowers can be made into tea. It has been used medicinally to treat rheumatism, upset stomachs, and colds. [5] The plant was used medicinally by several Native American groups, especially the leaves.
Symplocos tinctoria (the common sweetleaf, [3] horse-sugar, or yellowwood) is a deciduous or evergreen shrub or tree. It is recognized by pith of twigs chambered; by foliage not notably aromatic when bruised, leaves finely hairy beneath. Shrubs or trees to 17 m tall by 36 cm diameter at breast height. The largest first-year twigs are under 3 mm ...
Equisetum (/ ˌ ɛ k w ɪ ˈ s iː t əm /; horsetail) is the only living genus in Equisetaceae, a family of vascular plants that reproduce by spores rather than seeds. [2]Equisetum is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests.
The leaves are unstalked, slender, 2–10 centimetres (0.8–3.9 inches) long, and up to 1 cm (0.4 in) wide, with a coarsely toothed margin. They grow in an alternate spiral up the stem, and the lower ones wither early. The flower heads are produced in dense inflorescences and are 1 cm (0.4 in) in diameter.
The leaves are dark green, palmately compound with five (rarely seven) leaflets. Each leaflet is 6–17 cm (2.4–6.7 in) long, with a finely toothed margin and (particularly in spring) downy surfaces. The leaves are tender and prone to damage from both spring freezing or snow and summer heat and desiccation. [citation needed]
The flowering spikes, rubbed with a little sugar, are made into pills, and given internally to people bitten by mad dogs. The leaves, taken fresh and reduced to a pulp, are considered a good remedy when applied externally to the bites of scorpions. The ashes of the plant yield a considerable quantity of potash, which is used in washing clothes ...
The organisms first appear in the fossil record during the late Devonian, [1] a time when land plants were undergoing a rapid diversification, with roots, seeds and leaves having only just evolved. (See Evolutionary history of plants ) However, plants had already been on the land for almost a hundred million years, with the first evidence of ...
The common name comes from the leaf's supposed resemblance in shape to a colt's foot. [10] It is a 16th-century translation of the medieval Latin name pes pulli, meaning "foal's foot". [11] Other common names include tash plant, ass's foot, bull's foot, coughwort (Old English), [12] farfara, foal's foot
