PARTS USED Bark of the root and stalk, leaves. HISTORY Members of the amazonic jungle tribes have used it for hundreds of years. Cooked bark and root are used for the treatment of inflammatory diseases and neoplasie and in high dosages, it is also used as a contraceptive. The botanists consider Uncaria tomentosa, a widely studied plant, as original from the tropics of South America. Wagner et al showed in 1985 that it possesses stimulating action in the phagocytosis. Aquino and De Simone confirmed in 1989 its antiviral action through in-vitro studies. DESCRIPTION Uncaria tomentosa (Willd) D.C., known commonly as catís claw, is a large climbing shrub (approximately 20 meters high), belonging to the Rubiaceae family. The young branches have asquare shape. The branches have strong, 2 cm. long by 0.4 cmto 0.6 cm wide, woody thorns that point down, not entwined. Its fruits are brownish and fuzzy, the first leaves are reddish. It has two growing stages, in its first year it goes through the first stage, being a grassy plant, climbing but not helicoidal (it supports itself to other plants by means of its "claws" only). The claws are in clusters of three and born in the base of the leaves (bud). These claws begin to surge when the roots, in form of a rhizome have stored sufficient quantities of moisture and nutrients to survive in a warm environment. At this time the leaves have a short life span, they are oblong, but wide enough to have an elliptic shape, from 6 to 12 cm long. Here the claws are considered unicidulade acillars earrings in number of three and are similar to a cat¥s claw. After the second or third year, the plant becomes woody and the trunk shows a characteristic twisted appearance. This species grows forming frequent entangled vines in the thickness of the jungle, thus first described as Nauclea aculeata HBK, with more than 60 species (J. Soukup), growing in the edge of the high Amazon (high forests with abundant sunlight between 300 and 800 m.a.s.l. in the Perené valley, the Paucartambo rivers and in the Salt Hill) . According to some authors, there are three varieties of Uncaria tomentosa (Willd) D.C., but have no major differences between one another. These differences can be observed looking at the color of the recently cut bark and the color of the root. This way we can distinguish the three kinds, according to the color of fresh Liber (milky fiber), with gray ñwhitish, brown- yellowish and dark red. BOTANICAL DESCRIPTION TRUNK: Clearly distinguished by the pink color of its bark. Its bark can be yellowish when it is fresh; golden reddish yellow when it is dry. LEAVES: The primary ones are reddish, of short duration, with an oblong shape, so wide that it can be called elliptic, measuring from 6 to 12 centimeters in length, simple, of opposite disposition and with stipules of varied aspect that can be velvety and sometimes fuse each other. Sometimes they reach the same size as the older leaves forming "foliate verticiles". The claws born in the base of the leaves are considered "unicidulade acilary" earrings, similar to a catís claw. The topside is opaque, dark yellowish green and the underside is fuzzy or with a venous appearance, oblong and a membranous flat surface. FLOWERS: Hermaphrodite, fragrant, they can be "sessiles" or "peduncle", solitary or grouped in clusters, forming "capilated" inflorescence. The flowers are actinomorphes in the first period and then cigomorphes. Tubular chalice or toothed infundibuliform . Smooth/hairless corolla, with four or five white lobules, obtuse, very fuzzy. The stamen is inserted in the throat of the corolla Genie with infero ovary, bilocular, bicarpelar, multiovular. FRUIT: Brownish color, fuzzy and dry, 3,5 to 4 centimeters long, fusiform, bivalve.The seeds have meaty albumen, cartilaginous or corneous, sometimes rudimentary or reduced in size. POPULAR USES

They assumed, also that crop time and the consequent chemical changes could be one of the reasons for the variation in the composition of similar samples of Uncaria. QUINOVIC ACID, GLYCOSIDES, TRYPTERPHENES AND ESTEROIDAL FRACTIONS The glycosides of quinovic acid have common structural characteristic. The "aglicon" is the quinovic acid that has hydroxi group in C-3, an unsaturated bond (C-C) in C-12 and two carboxyle groups in C-27 and C-28. The carbohydrate part is joined through oxygen in C-3, conforming the true glycoside, while that of the carboxyles C-27 and C-28 form sters with carbohydrate units. Following, we detail the summary of the research that indicate the presence of these compounds of Uncaria tomentosa:
From quinovic acid 1, 2 and 3.
(The three most widely known are the glycosides 1, 2 and 3)

PHARMACOLOGY Numerous studies of Uncaria tomentosa have been conducted worldwide, more so in the 80s, primarily in Italy, Austria and Peru and show that this is a species with mainly antiinflammatory and immune stimulant properties, although the final conclusions about responsible metabolites or the active compounds have yet to be identified.
In this research, the above-mentioned German scientists devoted their time to trials with isolated alkaloids and in groups, in order to clarify the effect of Uncaria in the phagocytic activity of leukocytes in vitro (study of the immune stimulant activity),. Thus, by the use of the Granulocites (Granuloziten) technique invented by Brandt in 1967 (which is used to measure the defense activity of the white blood cells), they observed that ethyl acetate extract from Uncaria tomentosa (Willd) DC, after alkalinization, had a better phagocytic action than those extracts from ethanol without previous treatment (between 20% and 35% increase). In this test Isopteropodine HCI had the highest index of effectiveness with respect to other alkaloids singly and/or in combinations. Similarly, they used the Luminescence technique (Chemolunin) to determine the grade of phagocytosis by light enhancers. Isopteropodine HCI had the highest phagocytic effectiveness; Pteropodine alkaloids, isomitraphyllline and isorhynchophylline showed 50% of phagocytic effectiveness. Similarly, the result showed that Mitraphylline and Rhynchophylline alkaloids did not show similar properties. Another applied test in this study by German scientists, was the carbon ñ clearance test (according to Biozzi) using rats. This test is used to determine the speed at which reticulo-endothelial tissue reacts to some foreign substance. They noted a significant phagolitic action in those rats that were subject to a watery macerate with alkaloid content in a concentration of 10 mg/kg. Those macerated with low concentration of alkaloids had minimal action. Pure mixed alkaloids showed no effect, unless in the presence of a 10% cathequine solution. Similarly, a better response was shown with increasing levels of isopteropodine alkaloids. CONCLUSIONS The efficiency of the extract of the vegetal specie Uncaria tomentosa (Willd) DC, depends on the presence of three important factors:
The above explains the traditional ancestral Peruvian practice of using whole plant extracts for optimal medicinal results. In another study at San Marcos University Lima-Peru (7) they determined the anti- inflammatory effect of glycosidic extract of Uncaria tomentosa (Willd) D.C., compared to the anti-inflammatory effect of Indomethacine, Piroxican and Dexametasone, by using the Edema Pedal anti-inflammatory method by Carragenina (to induce inflammation by subplantar injections of 1% carragenina solution of mucopolisaccharide extracted from red seaweed, in the hind feet of albino rats, producing edema that is measured pletismographically). Results are shown in the following chart:
Half values of anti-inflammatory efficiency (expressed in average)
Source: (7)
As can be appreciated in the above table, the glycosidic extracts reported 83,3 % of anti-inflammatory efficiency with a doses of 0,11 mg/kg of weight versus the controls that showed an inhibition average of 73,9%, allowing us to conclude that the glycosidic extracts of catís claw used at the most common levels, is effective in the anti-inflammatory processes. Similar studies made Rengifo D. And Albino E. showed a higher effectiveness of lyophilized products (36,8%) and atomized (35,8%) than the micropulverized (28,3%), No differences were apparent between the first two presentations
The following trials were conducted:
The following results were obtained:
Due to these bio trials, the researchers assumed that the antimutagenic significant activity of the extracts and fractions of Uncaria tomentosa (Willd) D.C. could be due to an antioxidant effect.
