Iochroma cyaneum in flower:
The psychoactive use of this beautiful and rare plant was discovered from Richard Evans Schultes (Iochroma fuchsioides) in the Sibundoy valley of Colombia. It can be found in the andine mountains at an elevation of around 2200m. The habitat of Iochroma cyaneum is also Colombia.
The dried and fresh leaves and flowers are smoked, infused as tea or boiled. The shamans of the Kamsá in Colombia take this plant when they are confronted with cases, which are very hard to diagnose. Iochroma fuchsioides is used as an additive to ayahuasca and as a narcotic during complicated births and digestive problems.
Curanderos from North-Peru use a Iochroma sp. (Contrahechizo) as additive to the San Pedro- brew.
The intoxication is said to last for days... (?)
In many Iochroma species, including I. fuchsioides, Withanolides were found, but no alkaloids like in other Solanaceae.
The sedative Withania somnifera, widely distributed in Irak and India also contains Withanolides like Withaferine A, which has cholinergic and GABAergic effects...
Jaborosa integrifolia has beautiful flowers and also contains Withanolides like Jaborosalactone B.
