Erva tostão is called punarnava in India, where it has a long history of use by indigenous and tribal people and in Ayurvedic herbal medicine systems.

TRIBAL AND HERBAL MEDICINE USES

The roots of erva tostão have held an important place in herbal medicine in both Brazil and India for many years. G. L. Cruz, one of Brazil’s leading medical herbalists, reports erva tostão is “a plant medicine of great importance, extraordinarily beneficial in the treatment of liver disorders.” It is employed in Brazilian herbal medicine to stimulate the emptying of the gallbladder, as a diuretic, for all types of liver disorders (including jaundice and hepatitis), gallbladder pain and stones, urinary tract disorders, renal disorders, kidney stones, cystitis, and nephritis. In Ayurvedic herbal medicine systems in India, the roots are employed as a diuretic, digestive aid, laxative, and menstrual promoter and to treat gonorrhea, internal inflammation of all kinds, edema, jaundice, menstrual problems, anemia, and liver, gallbladder, and kidney disorders. Throughout the tropics, erva tostão is considered an excellent natural remedy for guinea worms — a bothersome tropical parasite that lays its eggs underneath the skin of humans and livestock; the eggs later hatch into larvae or worms that eat the underlying tissue. The roots of the plant are normally softened in boiling water and then mashed up and applied as a paste or poultice to the affected areas to kill the worms and expel them from the skin.

PLANT CHEMICALS

Novel plant chemicals have been found in erva tostão, including flavonoids, steroids, and alkaloids, many of which drive its documented biological activities. The novel alkaloids found in erva tostão have been documented with immune modulating effects. In one study, the alkaloid fraction of the root evidenced a dramatic effect in reducing an elevation of cortisol levels under stressful conditions (cortisol is an inflammatory chemical produced in the body in an immune response). Simultaneously, the alkaloids (and a whole root extract) also prevented a drop in immune system performance indicating an adaptogenic immune modulation activity, which might suggest it could be helpful in preventing adrenal exhaustion.

The main plant chemicals in this plant include: alanine, arachidic acid, aspartic acid, behenic acid, boeravinone A thru F, boerhaavic acid, borhavine, borhavone, campesterol, daucosterol, ecdysone, flavones, galactose, glutamic acid, glutamine, glycine, hentriacontane, heptadecyclic acid, histidine, hypoxanthine, liriodendrin, oleaic acid, oxalic acid, palmitic acid, proline, punarnavine, serine, sitosterols, stearic acid, stigmasterol, syringaresinol, threonine, triacontan, ursolic acid, and valine.

BIOLOGICAL ACTIVITIES AND CLINICAL RESEARCH

Erva tostão has long been used in traditional medicine systems as a diuretic (to increase urination) for many types of kidney and urinary disorders. The diuretic action of erva tostão has been studied and validated by scientists in several studies. Researchers showed that low dosages (10–300 mg per kg of body weight) produced strong diuretic effects, while higher dosages (more than 300 mg/kg) produced the opposite effect—reducing urine output. Later research verified these diuretic and antidiuretic properties, as well as the beneficial kidney and renal effects of erva tostão in animals and humans. Research indicates that a root extract can increase urine output by as much as 100 percent in a twenty-four-hour period at dosages as low as 10 mg per kg of body weight.

The worldwide use of erva tostão for various liver complaints and disorders was validated in three separate studies. These indicated that a root extract provided beneficial effects in animals by protecting the liver from numerous introduced toxins and even repairing chemical-induced liver and kidney damage. In other clinical studies with animals, erva tostão extracts demonstrated smooth muscle and skeletal muscle stimulant activities in frogs and guinea pigs; anti-inflammatory actions in rats; hypotensive actions in dogs as well as in vitro hypotensive actions; antispasmodic actions in frogs and guinea pigs; analgesic activities in mice; and antiamebic actions in rats. In two studies with monkeys, a root extract was reported to reduce bleeding and uterine hemorrhaging commonly associated with wearing contraceptive IUDs. The traditional use of erva tostão for convulsions was verified by scientists in two studies, demonstrating that a root extract provided anticonvulsant actions in mice. In vitro testing of erva tostão confirmed its antibacterial properties against gonorrhea (another traditional use), as well as Bacillus, Pseudomonas, Salmonella and Staphylococcus. It was also shown to possess antiviral actions against several viral plant pathogens.

CURRENT PRACTICAL USES

Many of these animal studies help to explain erva tostão’s long history of different uses in natural medicine. Clearly, it has played an important role in the herbal practitioner’s medicine chest of natural remedies for many maladies in both South America and India. It is an effective natural remedy, especially for the liver and kidneys, which is deserving of much more attention and use here in the United States. Several research groups studying various biological activities of erva tostão have shown the safety of the plant — indicating no toxicity of root and leaf extracts taken orally by mice at up to 5 g per kg of body weight. Another group of scientists studied the effects of erva tostão on pregnant rats and reported that it had no abortive effects and no embryotoxic or teratogenic (fetal death or birth defect) activity.

From Wikipedia -

The Australian Green Tree Frog, simply Green Tree Frog in Australia, White’s Tree Frog, or Dumpy Tree Frog (Litoria caerulea) is a species of tree frog native to Australia and New Guinea, with introduced populations in New Zealand and the United States. The species belongs to the genus Litoria. It is physiologically similar to some species of the genus, particularly the Magnificent Tree Frog (Litoria splendida) and the Giant Tree Frog (Litoria infrafrenata).

The Green Tree Frog is larger than most Australian frogs, reaching 10 centimetres (4 inches) in length. The average lifespan of the frog in captivity, about sixteen years, is long in comparison with most frogs. Green Tree Frogs are docile and well suited to living near human dwellings. They are often found on windows or inside houses, eating insects drawn by the light.

Due to its physical and behavioural traits, the Green Tree Frog has become one of the most recognisable frogs in its region, and is a popular exotic pet throughout the world. The skin secretions of the frog have antibacterial and antiviral properties that may prove useful in pharmaceutical preparations.

The Green Tree Frog shares the Litoria genus with dozens of frog species endemic to Australasia. The common name of the species, "White’s Tree Frog", is in honour of John White’s first description in 1790. The Green Tree Frog was the first Australian frog scientifically classified.

The species was originally called the "blue frog" (Rana caerulea) despite its green colour. The original specimens White sent to England were damaged by the preservative and appeared blue. The colour of the frog is caused by blue and green pigments covered in a yellow layer; the preservative destroyed the yellow layer and left the frog with a blue appearance. The specific epithet, caerulea, which is Latin for blue, has remained. The frog is also known more simply as the "Green Tree Frog." However, that name is often given to the most common large green tree frog in a region, for example, the American green tree frog (Hyla cinerea).

The Green Tree Frog can grow up to 10 centimeters (4 inches) in length. Its color depends on the temperature and color of the environment, ranging from brown to green; the ventral surface is white. The frog occasionally has small, white, irregularly shaped spots on its back, up to five millimeters in diameter, which increase in number with age. The frog has large discs at the end of its toes, of about five millimeters in diameter at maturity. These help the frogs grip while climbing and allow them to climb vertically on glass. The eyes are golden and have horizontal irises, typical of the Litoria genus. The fingers are about one-third webbed, and the toes nearly three-quarters webbed. The tympanum (a skin membrane similar to an eardrum) is visible.

The Green Tree Frog is sometimes confused with the Magnificent Tree Frog (Litoria splendida), which inhabits only north-western Australia and can be distinguished by the presence of large parotoids and rostral glands on the head. The Giant Tree Frog (Litoria infrafrenata) is also sometimes confused with the Green Tree Frog. The main difference is a distinct white stripe along the edge of the lower jaw of the Giant Tree Frog, which is not present in the Green Tree Frog.

The tadpole’s appearance changes throughout its development. The length of the species’ tadpoles ranges from 8.1 millimeters (once hatched) to 44 millimeters. They are initially mottled with brown, which increases in pigmentation (to green or brown) during development. The underside begins dark and then lightens, eventually to white in adults. The eggs are brown, in a clear jelly and are 1.1–1.4 millimeters in diameter.

Although frogs have lungs, they absorb oxygen through their skin, and for this to occur efficiently, the skin must be moist. A disadvantage of moist skin is that pathogens can thrive on it, increasing the chance of infection. To counteract this, frogs secrete peptides that destroy these pathogens. The skin secretion from the Green Tree Frog contains caerins, a group of peptides with antibacterial and antiviral properties. It also contains caerulins, which have the same physiological effects as CCK-8, a digestive hormone and hunger suppressant. Several peptides from the skin secretions of the Green Tree Frog have been found to destroy HIV without harming healthy T-cells.

The Green Tree Frog is native to northern and eastern regions of Australia and to southern New Guinea. Distribution is limited mostly to areas with a warm, wet tropical climate. In New Guinea, the Green Tree Frog is restricted to the drier, southern region. Its range spans from Irian Jaya to Port Moresby, and is most abundant on Daru Island. There have been isolated records in northern New Guinea, however this is thought to have been through introduction by humans. The International Conservation Union (IUCN) suggests "scattered locations" in both New Guinea and Indonesia.

The species has been introduced to both the United States and New Zealand. In the United States, it is restricted to two regions within Florida, where it was possibly introduced through the pet trade. Only small populations have been found in Florida, and it is unknown whether they have caused any ecological damage as an invasive species. In New Zealand, a population was once present; however, there have been no sightings since the 1950s.

Green Tree Frogs are very docile. They are nocturnal and come out in early evenings to call (in spring and summer) and hunt at night. During the day they find cool, dark, and moist areas to sleep. During winter, Green Tree Frogs do not call and are not usually seen.

Depending on their location, Green Tree Frogs occupy various habitats. Typically, they are found in the canopy of trees near a still-water source. However, they can survive in swamps (among the reeds) or in grasslands in cooler climates. Green Tree Frogs are well known for inhabiting water sources inside houses, such as sinks or toilets. They can also be found on windows eating insects. They will occupy tanks (cisterns), downpipes (downspouts), and gutters, as these have a high humidity and are usually cooler than the external environment. The frogs are drawn to downpipes and tanks during mating season, as the fixtures amplify their call.

The species’ call is a low, slow Brawk-Brawk-Brawk, repeated many times. For most of the year, they call from high positions, such as trees and gutters. During mating season the frogs descend, although remaining slightly elevated, and call close to still-water sources, whether temporary or permanent. Like many frogs, Green Tree Frogs call not only to attract a mate. They have been observed calling to advertise their location outside the mating season, usually after rain, for reasons that are uncertain to researchers. They will emit a stress call whenever they are in danger, such as when predators are close or when a person steps on a log in which a frog resides.

The species’ diet consists mainly of insects and spiders, but can include smaller frogs and even small mammals. Frog teeth are not suited to cutting up prey, so the prey must fit inside the mouth of the frog. Many frogs propel their sticky tongues at prey. The prey sticks, and is consumed. A Green Tree Frog will use this technique for smaller prey; however for larger prey, it pounces, then forces the prey into its mouth with its hands.

The frog has a few native predators, among them snakes and a few species of lizards and birds. Since the European settlement of Australia, non-native predators have been introduced, primarily dogs and cats. The species has an average life expectancy in captivity of sixteen years, but some have been known to live for over twenty years, which is long for a frog. The average life expectancy in the wild is lower than in captivity, due to predation.

As a pet
The Green Tree Frog is one of the most popular pet frogs throughout the world. Its docile nature, often cartoon-like appearance, and long life expectancy make it an attractive choice for exotic-pet owners. It is also one of the easier frogs to care for: their diet is broad and they have a strong resistance to disease. One problem commonly associated with keeping this species as a pet is overfeeding; Green Tree Frogs tend to become obese if overfed. In the wild, exertion of energy is required for a frog to capture its prey. However, in captivity they are usually given live feed in a confined space. This lessens the activity needed for feeding, resulting in weight gain. An overweight member of the species will deposit fat layers over the top of the head and body, giving it "dumpy" appearance. Thus the name, "Dumpy Tree Frog."

Conservation
Australian law gives protected status to the Green Tree Frog – along with all Australian fauna – under the federal Environment Protection and Biodiversity Conservation Act 1999. The IUCN lists it as a "least concern" species, given its broad range and population, balanced habitats, and because it is likely not declining fast enough for more threatened status.

Much of the Green Tree Frog’s natural habitat has been destroyed. Also, some of the frogs have been found infected with chytrid fungus (causing chytridiomycosis). These two factors associated with the general decline in frog populations in Australia threaten to reduce the population of the Green Tree Frog. However, because of the long life expectancy of this species, any effects of a reduced reproduction rate will take longer to spot than they would in a species with a shorter life expectancy.
