prickly ash, name for two deciduous shrubs or small trees (Zanthoxylum americanum and Z. clava-herculis) of the family Rutaceae (rue family). They are native to E North America and have prickly twigs and foliage similar to that of the unrelated ash tree. A pungent aromatic principle in the bark has been used as a home remedy for various ailments including rheumatism and toothaches (hence the local name toothache tree). Z. clava-herculis, of more southerly distribution, is also known as Hercules'-club. Both Hercules'-club and prickly ash are names sometimes used for an unrelated plant of the family Araliaceae (ginseng family). Other Zanthoxylum species are the sources of Sichuan and Sansho peppercorns (Z. simulans and Z. piperitum, respectively) and of satinwood (Z. flavum). Prickly ash of the genus Zanthoxylum is classified in the division Magnoliophyta, class Magnoliopsida, order Sapindales, family Rutaceae. The family Araliaceae belongs to the order Apiales.



Source: Zanthoxylum americanum Mill. or Z. clava-herculis L. (sometimes erroneously spelled Xanthoxylum) (Family Rutaceae).

Common/vernacular names: Angelica tree, northern prickly ash, pepper wood, toothache tree, and yellow wood (Z. americanum); Hercules' club, prickly yellow wood, sea ash, and southern prickly ash (Z. clava-herculis); toothache tree and xanthoxylum.

Both species are shrubs or small trees growing to about 3 m high with prickly stems and petioles; native to North America. Northern prickly ash (Z. americanum) grows from Quebec south to Mississippi and west to Oklahoma, while southern prickly ash (Z. clava-herculis) grows farther to the south, from southern Virginia to Florida, Texas, and perhaps Mexico. Part used is the dried bark.

Zanthoxylum (including Z. fagara) is a genus of about 250 species of deciduous and evergreen trees and shrubs in the citrus or rue family, Rutaceae, native to warm temperate and subtropical areas worldwide. Common names include Prickly-ash and Hercules' Club.

The fruit of several species are used to make the spice Sichuan pepper. They are also used as bonsai trees. Historically, the bark was widely used for toothache, colic, and rheumatism.[3]

Selected species

(syn. Fagara ailanthoides (Sieb. & Zucc.) Engler[5])
  • Zanthoxylum alatum Roxb. – Winged Prickly-ash.
(cf. syn under Z.armatum)
(syn. Z. planispinum Sieb. & Zucc.; Z. alatum sensu Forbes & Hemsley, Rehder & Wilson, non Roxburgh; Z. alatum var. planispinum Rehder & Wilson[5])
(syn. Fagara mantchurica (J.Benn. ex Daniell) Honda, F. schinifolia (Seib. & Zucc.) Engl.)[9]

Formerly placed here

  • Eleutherococcus trifoliatus (L.) S.Y.Hu (as Z. trifoliatum L.)
  • Melicope lunu-ankenda (Gaertn.) T.G.Hartley (as Z. roxburghianum Cham.)
  • Melicope pteleifolia (Champ. ex Benth.) T.G.Hartley (as Z. pteleifolium Champ. ex Benth.)[12]

Taxonomy

The generic name is derived from Greek words ξανθὸς (xanthos), meaning "yellow," and ξύλον (xylon), meaning "wood." It refers to a yellow dye made from the roots of some species.[13] The Takhtajan system places the genus in the subfamily Rutoideae, tribe Zanthoxyleae,[14] while Germplasm Resources Information Network places it in the subfamily Toddalioideae and does not assign it to a tribe.[1] The once separate genus Fagara is now included in Zanthoxylum.[15]

Uses

Many Zanthoxylum species make excellent bonsai and in temperate climates they can be grown quite well indoors. Zanthoxylum beecheyanum and Zanthoxylum piperitum are two species commonly grown as bonsai.

Culinary use

Spices are made from a number of species in this genus, especially Zanthoxylum piperitum, Z. simulans, Z. bungeanum, Z. schinifolium Z. nitidum, Z. rhetsa, Z. alatum, and Z. acanthopodium. Sichuan pepper is most often made by grinding the husks that surround Z. piperitum berries.[16] In the states of Maharashtra, Karnataka, and Goa in Western India, the berries of Z. rhetsa are sun-dried and added to foods such as legumes and fish. Because the trees bear fruit during the monsoon season, the berries are associated with the concurrent Krishna Janmashtami festival.[17] It is called timur or timbur in Nepal, Darjeeling and Sikkim and is used widely to make a tingling dip, especially for boiled food like potatoes and yams.

Ecology

Zanthoxylum species are used as food plants by the larvae of some Lepidoptera species including The Engrailed.
