Artocarpacese is a natural order of plants, the bread-fruit order, by some botanists ranked as a sub-order of the Urticaceae or nettles. They are trees or shrubs, with a milky juice, which in some species hardens into caoutchouc, and in the cow-tree (Brosimum Galactodendron) is a milk as good as that obtained from the cow. Many of the plants produce an edible fruit, of which the best known is the bread-fruit (Artocarpus).

The four-angled stems have opposite, ovate, pointed and toothed leaves, the lower with blades longer than their stalks. The flowers are greenish, small, with four petals and borne in loose axillary spikes. Male and female flowers are borne on separate plants.

Dorsetenia is a genus of plants of the natural order Urticaceae or nettles, found in tropical America. They have their naked flowers buried in a flat, fleshy, somewhat concave receptacle. Dorsetenia Contrayerva and other species have a stimulant and tonic rhizome, which was formerly used medicinally under the name of contrayerva.

The hop (Humulus Lupulus) is a native British and European plant of the hemp family Cannabiaceae, natural order Urticaceae. The root is perennial giving out several herbaceous, rough, twining stems with large lobed leaves. The the fertile flowers are green; the fruit is a catkin and the catkins are added to beer to give it its aromatic and bitter flavour. The young shoots are sometimes boiled and eaten like asparagus; the fibres of the old stems make good cords and were formerly used. The use of the hop catkins depends upon a peculiar bitter substance which they contain, called lupulin, which is a yellow powder, containing a bitter principle and a volatile oil. The lupulin constitutes from 10 to 12 per cent by weight of the catkin, and the bitter principle forms from 8 to 12 per cent of the lupulin. Having tonic, stomachic, and narcotic properties hops were often used medicinally. Pillows stuffed with hops are used to induce sleep.
