Ayapana (Ayapana triplinervis)
Ayapana is traditionally used in Brazilian herbal medicine for queasy stomachs, indigestion, diarrhea, fever, headaches, insomnia, nausea and vomiting, and stomach ulcers. Scientists over the years have reported that ayapana possesses analgesic, antibacterial, anticoagulant, antifungal, antiparasitic, anthelminitic, CNS depressant, and sedative actions in various animal and laboratory studies.

Condurango (Marsdenia cundurango)
In Brazilian herbal medicine condurango is used for appetite loss, dyspepsia, gastralgia, gastritis, neuralgia, stomachaches, stomach cancer, stomach ulcers, and rheumatism. Its use as a digestive aid was studied and validated in the mid-1980s when scientists reported that it increased various digestive enzymes and juices in the stomach. Other research suggests that condurango is antibacterial, anti-inflammatory, anti-leukemic, antioxidant, and antitumorous.

Canchalagua (Schkuhria pinnata)
Canchalagua is often relied on in Peruvian herbal medicine systems to ease nausea and stomachaches, and as a general digestive aid. Scientists have reported that canchalagua has antibacterial, antifungal, anti-inflammatory, antimalarial, antispasmodic, and anti-yeast actions.

Matico (Piper aduncum)
Matico is traditionally used by Indians of the Peruvian Amazon for gastritis, vomiting, fever, inflammation, diarrhea, menstrual colic, internal infections and as a postpartum tonic. Despite any scientific validation, matico still remains a main-stay in herbal medicine practices in South America for many types of digestive problems and it is quite well known and well respected for those types of conditions. In laboratory research the plant has been reported with antibacterial, anticandidal, antifungal, antileishmaniasis, antiyeast, antiviral, and cytotoxic properties.

Piri-Piri (Cyperus articulatus)
Piri-piri has a long history of use in herbal medicine systems in South America as a common remedy for nausea, vomiting, stomachaches, and intestinal gas throughout the continent. Piri-piri has been documented with anti-epileptic and anticonvulsant actions, as well as sedative actions in animal studies. It was also reported with antioxidant actions, antibacterial actions against Staphylococcus and Pseudo-monas, and anti-yeast actions against Candida. It passed a preliminary screening test to predict antitumor actions in other research.
