Hunting and Hallucinogens: The use psychoactive and other Plants to improve the Hunting ability of dogs
Abstract
Ethnopharmacological relevance
Cultures
throughout the world give plants to their dogs in order to improve
hunting success. These practices are best developed in lowland Ecuador
and Peru. There is no experimental evidence for the efficacy of these
practices nor critical reviews that consider possible pharmacological
effects on dogs based on the chemistry of the ethnoverterinary plants.
Aim
This
review has three specific aims: 1. Determine what plants the Ecuadorian
Shuar and Quichua give to dogs to improve their hunting abilities, 2.
Determine what plants other cultures give to dogs for the same purpose,
and 3. Assess the possible pharmacological basis for the use of these
plants, particularly the psychoactive ones?
Methods
We
gathered Shuar (Province of Morona-Santaigo) and Quichua (Napo and
Orellano Provinces) data from our previous publications and field notes.
All specimens were vouchered and deposited in QCNE with duplicates sent
to NY and MO. Data presented from other cultures derived from published
studies on ethnoveterinary medicine. Species names were updated, when
necessary, and family assignments follow APG III (Angiosperm Phylogeny Group 2009). Chemical data were found using PubMed and SciFinder.
Results
The
Shuar and Quichua of Ecuador use at least 22 species for
ethnoveterinary purposes, including all but one of their principal
hallucinogens. Literature surveys identified 43 species used in other
cultures to improve hunting ability. No published studies have examined
the pharmacological active of these plant species in dogs. We, thus,
combined phytochemical data with the ethnobotanical reports of each
plant and then classified each species into a likely pharmacological
category: depuratives/deodorant, olfactory sensitizer, ophthalmic, or
psychoactive.
Conclusions
The
use of psychoactive substances to improve a dog’s hunting ability seems
counterintuitive, yet its prevalence suggests that it is both adaptive
and that it has an underlying pharmacological explanation. We
hypothesize that hallucinogenic plants alter perception in hunting dogs
by diminishing extraneous signals and by enhancing sensory perception
(most likely olfaction) that is directly involved in the detection and
capture of game. If this is true, plant substances also might enhance
the ability of dogs to detect explosives, drugs, human remains, or other
targets for which they are valued.
