Common hop is a dioecious, perennial herbaceous
climbing plant which sends up new shoots in early spring and dies back
to the cold-hardy rhizome in autumn. Stems are annual, slender,
climbing, up to 9 m in length, often with stout hooked hairs. Leaves
are oppositely arranged, heart-shaped, 3-5-lobed, margins toothed,
stalk slightly fleshy with stout hooked hairs. Plant is dioecious with
unisexual flowers on separate plants, but occasionally monoecious
plants occur, in which case male or female flowers are often infertile.
The flowers are wind-pollinated. Female inflorescence are cone-like,
2.5-5 cm long, whereas male flowers are borne in long racemes. The
flower cones of the plant, known as hops, are used in the production of
beer to impart bitterness and flavor, and for their preservative
qualities. Common Hop is native to the temperate Northern Hemisphere,
and is widely cultivated around the world.
Medicinal uses:
Dried female hops have historically been used for its sedative effects
on the central nervous system due to its methylbutenol content as a
treatment for stress, anxiety and insomnia. Hops have been studied for
anti-viral properties and anti-micro bacterial properties. They also
contain numerous various flavonoids, and they have been studied for
containing estrogen precursors as well.
