The roots of M. hostilis, which is not the common houseplant M. pudica ("sensitive plant"), contain 0.57% DMT and are used by Indians of Pernambuso State in Brazil as part of their Yurema cult (Pachter et al. 1959, Schultes 1977, (Meckes-Lozoya et al. 1990). The root bark can be powdered e.g. in a coffee grinder, boiled in 30% lemon juice for an hour and strained through a paper filter to produce liquid for ingestion. 8-20 g of the root bark prepared this way has been reported to give a trip with nausea, both the intensity of the psychedelic effect and the nausea being strong at the 20 g dosage. An acid-base extraction method (involving e.g. hydrochloric acid, sodium hydroxide and petroleum ether with CaCO2 for drying) can be used to get DMT crystals, which can then be smoked (below, a recipe for Phalaris). As M. hostilis root bark is one of the most concentrated plant sources of DMT mild effects can be felt from smoking ground bark. M. scabrella contains DMT and N-methyltryptamine (De Moraes et al., 1990). Bark of M. verrucosa also contains DMT (Smith 1977).
Contains DMT (Leboeuf et al., 1977).
Both contain DMT (Smith 1977).
Natives of western Amazon add DMT- and N-methyltryptamine containing leaves of the vine D. cabrerana to a drink made from Banisteriopsis caapi, which contains beta-carbolines harmine and harmaline (Schultes 1977, Smith 1977). D. cabrerana is also known as Banisteriopsis rusbyana. 3-8 leaves of this plant can be boiled in water containing lemon juice for one or two hours and filtered to produce a relatively easily ingested liquid that is active when combined with MAO-inhibitors. With 6 leaves the psychedelic effect from such a brew has been reported to be strong, with minimal nausea compared to e.g. M. hostilis.
Contains 5-MeO-DMT as well as a beta-carboline (Jossang et al. 1991).
The bark contains 5-MeO-DMT (Holmstedt et al. 1980).
The bark resin of these trees is used to prepare hallucinogenic snuffs in northwestern Brazil by boiling, drying and pulverizing it. Sometimes leaves of a Justicia are added. The snuff acts rapidly and violently, "effects include excitement, numbness of the limbs, twitching of facial muscles, nausea, hallucinations, and finally a deep sleep; macroscopia is frequent and enters into Waika beliefs about the spirits resident in the drug." Snuffs made from V. theiodora bark contain up to 11% 5-MeO-DMT and DMT. Also leaves, roots and flowers contain DMT.

Amazonian Colombia natives roll small pellets of boiled resin in a evaporated filtrate of bark ashes of Gustavia Poeppigiana and ingest them to bring on a rapid intoxication (Smith 1977, Schultes 1977).

DMT has been isolated from Pandanus nuts growing in New Guinea (Barrau 1958, 1962).

Leaves, flowers and rhizomes contain DMT, bufotenine and related compounds (Ghosal et al. 1972).
Leaves of P. arundinacea and leaves and seedlings of P. aquatica contain DMT, 5-MeO-DMT and related compounds (Smith 1977). P. arundinacea plants are available from commercial suppliers.

Jim DeKorne (1996) has reported that strong varieties of P. Arundinacea can be processed simply with a wheatgrass juicer to yield a liquid that is potent enough for one teaspoon to be effective with MAOIs. He has prepared a potent smokable extract as follows: grass clippings are pulverized and water is added to make a pourable mixture, which is then acidified to about pH 5. The mix can then be heated overnight while evaporation is not allowed. The plant matter is separated by first using a cheesecloth and then a paper coffee filter. 10-15% of the mass of the resulting solution of a "defatting solvent" (e.g. methylene chloride, ether, chloroform, or naptha) is then added. After vigorous shaking the water containing the alkaloids is separated from the solvent. A base is added to the aqueous solution in small increments until the pH gets to about 9 or 10, which converts the alkaloids into their free base. Extraction is then performed four times with an organic solvent, comprising 10% of the mass of the solution, first after 24 hours and then at three weekly intervals, while the solvent layer takes on a darker tint (usually yellowish or reddish-brown). In total the extraction takes almost a month and the solution should be shaken at least twice a day between extractions. To isolate the alkaloids the solvent is finally evaporated from the combined extract fractions.

Rhizomes contain DMT (Wassel et al. 1985).

Psychotria leaves are added to a hallucinogenic drink prepared from Banisteriopsis caapi and B. rusbyana (which contain beta-carbolines) to strengthen and lengthen the effects in western Amazon. P. carthaginensis and P. viridis both contain DMT (Rivier, 1972). P. viridis seeds are available from commercial suppliers.
Bark contains 0.04% 5-MeO-DMT (Pachter et al. 1959).

Contains DMT (Abu Zarga, 1986).
Contains 5-MeO-DMT as well as 5-MeO-DMT-Oxide and a beta-carboline (Skaltsounis et al. 1983).
The leaves and branches contains up to 0.2% DMT (Kan-Fan 1970).
Contains DMT (Grina et al., 1982).
