...aber dank interaktiver Werbeeinblendung weiß ich nun, dass auch Coconut oil gegen Candida helfen soll.
Ich kann dir leider bei deiner Frage nicht weiterhelfen. Hast du dich schon einmal in einem gut sortierten Teeladen nach der Teesorte erkundigt?

How it works in the body
In the ever dwindling rain forests of South America may be found huge trees reaching upwards of 100 feet in height and frequently with a trunk circumference exceeding four feet! The leaves are deciduous, opposite, on yellow-green stems; they have five elliptic leaves of unequal size that can be either lanceolate or ovate shaped. These leaves are uniquely placed in whorls comparable to the fingers of someone's hand. They reside on stems that are dark green on top and yellowish-green below. The flowers vary in color depending on the species. They can range from blue and yellow to magenta and purple. They have yellow throats and are either bell-or funnel-shaped.
Pau d'arco, known as lapacho colorado in Argentina and Paraguay and as ipe roxo in Brazil, is a good example of the lure of the exotic. This South American native has been used medicinally by several indigenous groups. There are several species of Tabebuia, and most appear to be broad-leaved evergreen trees with very hard wood that resists decay. It may be difficult to determine precisely which species is being sold as pau d'arco tea.
Pau d'arco has a reputation for having been used by the Incas, although it is not native to the high Andes. It is said to be useful against cancer, diabetes, rheumatism, and ulcers, as well as several other ailments. Extracts have been used topically to treat Candida yeast infections. Overall, however, the research on pau d'arco does not offer strong support for most of the medicinal claims made for it. The part of the tree used is the inner bark, and the preparation made from it is sometimes termed taheebo.
Pau d'arco, or taheebo, contains a number of quinone compounds, including the naphthoquinone lapachol and the anthraquinone tabebuin. These and related compounds are assumed to be the active ingredients.
Lapachol has antibacterial activity, and a related compound fights off fungus and yeast. Lapachol has demonstrated activity against malaria, a property that would certainly be useful for people in the areas where Tabebuia species grow wild.
Test tube and animal research in the 1950s and 1960s indicated that taheebo extract and lapachol could slow the growth of certain tumors. The National Cancer Institute subsequently tested lapachol for anticancer activity in humans, with disappointing results. In human trials, it was difficult to attain therapeutically active levels of lapachol with oral administration, and when levels did get high enough, most people suffered serious adverse effects such as nausea and vomiting.
Taheebo extract has anti-inflammatory activity, at least in rats. Researchers have also found that it helps animals resist ulcers. In laboratory studies on human blood cells, lapachol had immunosuppressant effects at higher doses and immunostimulant activity at low doses.
Popular reports state that Indian tribal doctors in Brazil brew a tea from the inner bark of Tabebuia avellanedae or Tabebuia altissima, known respectively as lapacho colorado and lapacho morado, that is used to treat cancer as well as ulcers, diabetes, and rheumatism. Proponents also claim that pau d'arco is "a powerful tonic and blood builder" and is effective against rheumatism, cystitis, prostatitis, bronchitis, gastritis, ulcers, liver ailments, asthma, gonorrhea, ringworm, and even hernias. The drug is claimed to have been popular in the old Inca Empire, long before the Spanish invaded the New World. T. avellanedae is native to the warmer parts of South America, but T. altissima supposedly grows high in the Andes Mountains, where "not even the worst winter storms can blow it down." Such popular reporting leaves much to be desired. There is no plant with the scientific name Tabebuia altissima,. further, no species of Tabebuia grows high in the Andes. This remote habitat was apparently the creation of some advertising copywriter to make the drug sound more exotic. Although Tabebuia avellanedae is a name found in literature, the correct botanical designation of the species is Tabebuia impetiginosa (Mart. ) Standl.
Complicating the matter of origin even further is the fact that some pau d' arco herbal teas marketed in this country do not derive from the Tabebuia species at all, even though they are labeled as lapacho colorado or lapacho morado. Instead, they are stated to represent the bark of Tecoma curialis Solhanha da Gama, another closely related member of the same plant family. This probably makes little difference because the useful constituents and therapeutic activities, if any, are undoubtedly similar. It nevertheless leaves the botanical source of pau d'arco products unclear. The outstanding American botanical authority on this group of plants, the late Dr. A H. Gentry, speculated that probably all of the bark in question was being obtained from some lowland Tabebuia species.
Because of their commercial significance in the construction industry, Tabebuia woods have been examined in detail. In addition to such therapeutically uninteresting constituents as volatile oils, resins, bitter principles, and the like, they contain from 2 to 7 percent of a naphthoquinone derivative known as lapachol. Analyses of the barks of three Tabebuia species showed that, unlike the wood, they did not contain lapachol and dehydro-alfa-lapachone as their major naphthoquinone constituents. Depending on the species, these compounds were either present in traces or entirely absent. Three lapachol derivatives were instead detected; their physiological properties appear to be very similar to those of lapachol.
Lapachol does possess some anticancer properties. In 1968, it was shown to have significant activity against Walker 256 carcinosarcoma, particularly when administered orally to animals in which this tumor had been implanted. In later studies, lapachol was found to be active against other kinds of animal cancers, including Yoshida sarcoma and Murphy-Sturm lymphosarcoma. In trials with human cancer patients, however, as soon as effective plasma levels were attained, undesirable side effects were severe enough to require that the drug be stopped. These included moderate to severe nausea, vomiting, anemia, and a tendency to bleed. Animal and other laboratory studies have demonstrated that lapachol also possesses antibiotic, antimalarial, and antischistosomal properties, but scientific studies have not been done in humans because of the problem of toxicity. Pau d' arco is marketed in the United States as a tea or "dietary supplement," with no therapeutic claims made on product labels. Its lack of proven effectiveness, its potential toxicity, and its relatively high cost render its use both unwise and extravagant.
PARTS USED
Inner bark.
USES
Early cure-all - The Incas, the Callawaya in Brazil, and other Native South American peoples prized lapacho as a cure-all. They used it to treat a variety of conditions including wounds, fever, dysentery, intestinal inflammation, certain types of cancer, and snakebites.
Infections - Given the large number of active constituents in lapacho, it is not surprising that this beneficial herb is used in South America and by herbal practitioners throughout the world. It is an important, natural antibiotic for bacterial and viral infections, especially of the nose, mouth, and throat and is considered helpful for chronic conditions such as ME. Lapacho is also used to treat fungal conditions, including ringworm and yeast infections and is considered especially useful for treating chronic fungal conditions, including candidiasis.
Anti-inflammatory action - Lapacho reduces and relieves inflammatory problems, especially in the stomach and intestines. Lapacho is used to treat a wide range of inflammatory conditions, including cystitis, inflammation of the cervix, and prostatitis.
Cancer remedy - Lapacho is beneficial in the treatment of cancer, including leukemia. Clinical experience in Brazil, combined with its traditional use for cancer, suggests that lapacho should be more intensively researched for its therapeutic value in the treatment of this disease.
Other medical uses - Hantavirus, Toxic shock syndrome.
HABITAT AND CULTIVATION
An indigenous South American tree, pau d'arco grows well in mountainous terrains. In Peru and Argentina it is found growing high up in the Andes. Pau d'Arco is also found in low-lying areas (in Paraguay and Brazil), where it is thought to have originated. A number of Tabebuia species are used in herbal medicine. T. avellanedae is considered to be the most therapeutically effective, but T. impetignosa is the species that is most commonly available. Pau d'arco is not normally cultivated -the inner bark is collected from wild trees throughout the year.
RESEARCH
Antitumor properties - Pau d'Arco anticancer action is controversial, but research in Brazil, which started during the 1960s, indicates that the bark may be therapeutically useful in treating cancer and leukemia. Many of the herb's constituents playa part in counteracting the growth of tumors, notably pau d'arco, which inhibits the growth of tumor cells by preventing them from metabolizing oxygen.
Other research - Pau d'Arco is known to be strongly anti-inflammatory. It also counters the effects of diabetes (an action that is due in part to the constituent tecomine) and it lowers blood pressure.
CONSTITUENTS
The main active ingredient in this plant is the quinones, of which there are 18, the main ones being naphthoquinones, of which lapachol and a form of lapachone are some of the most important. The bioflavonoid quercetin, lapachenole, carnosol, indoles, coenzyme Q, alkaloids, and steroidal saponins.
HOW MUCH TO TAKE
Because the naphthaquinone active constituents are not water soluble, a tea from pau d'Arco bark is ineffective. Capsules or tablets providing 300 mg of powdered bark can be taken; usually three capsules are ingested three times per day.
SIDE EFFECTS AND CAUTIONS
High doses of lapachol can cause uncontrolled bleeding, nausea, and vomiting. Use of the whole bark is much safer than isolated lapachol-the whole bark has no known serious side effects. Pregnant or lactating women should avoid use of pau d'arco.
HOW IT WORKS IN THE BODY
Lapachol was isolated as early as 1882, and in 1956 its antibacterial action was confirmed by research in Brazil which makes Pao d' Arco a valuable natural antibiotic. Further tests showed derivatives of this constituent also had antifungal properties effective against ringworm, vaginal thrush, and gastrointestinal candidiasis. Carnosol is a strong antioxidant which mops up free radicals in the body, and is thought to be responsible for the reputation of Pao d' Arco as an anticarcinogenic. In addition, the indoles have been identified as being active in detoxifying the body from carcinogens. A form of lapachone has an antiviral action which has been used against viruses such as herpes simplex and polio, but has also been used against retroviruses which are particularly implicated in cancer, especially leukemia, and AIDS. Pao d' Arco also demonstrates activity against some tropical parasites, and the alkaloids show some evidence of benefit in diabetes. Its detoxifying element is used in skin complaints, and its anti-inflammatory action for conditions such as cystitis, prostatitis, and intestinal inflammation.
