Acacia

(ka´sh) ,The Herb Acacia Articles any plant of the large leguminous genus Acacia, often thorny shrubs and trees of the family Leguminosae (pulse family). Chiefly of the tropics and subtropics, they are cultivated for decorative and economic purposes. Acacias are characteristic of savanna vegetation and are especially numerous in the South African bushveld. The foliage often appears feathery because of the many small leaflets, but in some species leaflike flattened stems contain chlorophyll and take the place of leaves. Various Old World species (especially A. arabica and A. senegal ) yield gum arabic; other species, chiefly A. catechu, yield the dye catechu. Blackwood (A. melanoxylon) is valued in Australia for its hardwood timber. Other members of the genus are valuable for lac, for perfume and essential oils, and for tannins; some are used as ornamentals. The Australian acacias are commonly called wattles–their pliable branches were woven into the structure of the early wattle houses and fences and Wattle Day celebrates the national flower at blossoming time. Many wattles are cultivated elsewhere, particularly in California, as ornamentals for their characteristic spherical, dense flowers. The Central American bullhorn acacias (e.g., A. sphaerocephala) have large hollow thorns inhabited by ants that are said to feed upon a sweet secretion of the plant and in turn guard it against leaf-eating insects. The most common acacia indigenous to the United States is the cat's-claw (A. gregii) of the arid Southwest. The biblical shittim wood is thought to have come from an acacia. Various species of locust are sometimes called acacia, and acacias may be called mimosa; all are of the same family. Acacia is classified in the division Magnoliophyta, class Magnoliopsida, order Rosales, family Leguminosae.

Common names, Cape gum, Egyptian thorn, Gum Arabic tree, Gum acacia,
Gum Arabic,India gum tree,Bablah pods, Acacia bambolah.

Acacia is a small, spiny, leguminous tree or shrub. After the rainy season ends, the stem begins to exude gum, which is collected from December to June for marketing as gum Arabic. The acacia has alternate, bipinnate leaves and axillary racemes of yellow flowers arranged in globose heads. The fruit is an oblong pod.

Grows in sandy soil, mostly in tropical Africa

Acacia was a sacred wood for the ancient Hebrews. Moses used acacia wood in building the Ark of the Covenant and the sacred Tabernacle (see Exodus, chapters 25-40).

According to Near-Eastern Christian legend, a thorny species of acacia was used for Christ's crown of thorns.

Moapa Paiute name for acacia is "Pah oh pimb." Used for inflammation of the eyes, due to dust; vaqueros and travelers habitually carry acacia seeds and put 4 in each eye on retiring.

Gum Arabic's main effect is to form a protective, soothing coating over inflammations in the respiratory, alimentary, and urinary tracts. It is helpful for coughs, sore throat, and catarrh, eyewash, diarrhea, and dysentery. Sweetened, it is sometimes used for typhoid fever.

Acacia greggii
Taxonomy: Magnoliophyta (angiosperm), Magnoliopsida (dicot), Fabaceae (formerly Leguminosae)

Common names: catclaw, Gregg cat claw, cat's claw acacia, tear blanket, devils claw, paradise flower, long-flowered catclaw, Texas mimosa, uña de gato.

Acacia greggii is a member of the Fabaceae family; it is native to the Southwestern United States and northern Mexico. Catclaw occurs primarily in semi-desert grasslands and brushy range lands largely confined to washes. It is often found on the upper slopes of a bajada (Spanish for downhill) where moisture is more available than middle or lower bajada situations. Catclaw has the highest water requirements of several species of desert shrubs tested, partially explaining why although it is found in arid regions, is often confined to dry washes or stream bottoms with relatively shallow water tables.

Catsclaw a perennial, is characterized as being a 3 to 10 foot tall shrub but may develop into an upright tree 25 to 30 feet tall. It is often thicket forming and has numerous spreading, slender thorny branches. The brown, stout, "claw like" thorns are about 0.25 inch long. The bark is gray to black. Numerous creamy-yellow flowers occur in 1.25 to 2.5 inch long spikes. The stiff and papery gray-brown legume-type fruits are 2 to 5.5 inches long, 0.5 to 0.75 inch wide, curved or contorted, flattened and constricted between the seeds.

Propagation:

Catsclaw acacia reproduces sexually by producing an abundance of seeds. Vegetative regeneration (sprouting) occurs following damage to the above-ground portion of the plant. Catclaw acacia flowers are pollinated by insects and begin to produce seed between 4 to six years of age. It has shown varying success when transplanted. Seedlings can be nursery grown in tall containers to accommodate the deep root systems. In California, seed collected in the field exhibited good germination without any special treatment in fall or spring.

Catsclaw acacia has flowers in yellow, cylindrical spikes. The flowers and leaves of this plant resemble mesquite, but cats claw thorns are like rose thorns, broad at the base and curved backward while mesquite thorns are straight. The seed pods of the catsclaw split upon maturing mesquite pods do not.

Preparation:

Gather the pods when still green and dry the leaves and branches over a paper as the leaves often fall off while hanging. The longer distal roots, chopped into small segments while moist. The gum is gathered the same way as mesquite gum and the flowers are dried. The green leaves, stems, and pods are powdered for tea (standard infusion) or for topical application; the roots are best used as a cold standard infusion, warmed for drinking and gargling.

Medicinal Uses:
Pods are used for conjunctivitis in the same manner as mesquite pods and the gum, although catsclaw is harder to harvest it is used in the same way as mesquite gum. The powdered pods and leaves make an excellent infused tea (2-4 ounces of the standard infusion every three hours) for diarrhea and dysentery, as well as a strongly astringent hemostatic and antimicrobial wash. The straight powder will stop superficial bleeding and can also be dusted into moist, chafed body folds and dusted on infants for diaper rash. The flowers and leaves as a simple tea are good anti-inflammatory for the stomach and esophagus in nausea, vomiting, and hangovers. It is distinctly sedative. The root is thick and mucilaginous as a tea and is good for sore throat and mouth inflammations as well as dry raspy coughing.

People who have used this plant:
Catsclaw has been used by Native Americans for treating the sore backs and flanks of their horses. There has been no specific information on cultural practices concerning catsclaw. Most sources indicate that the plant has been used by many groups in the southwestern United States.
