Le post de lucid ne donne aucune info intéressante .
Sur une source qu'on ne peut cité ici il est dit :
Parmelia conspersa : Traditionally used by the Pima and Papago of South Arizona and North-West Mexico.
Ginkgo reports that the effects are similar to cannabis, although not quite. Effects lasts maybe two hours, and not very potent.
there are reports that it is highly active and on par with good cannabis
Contains usnic acid, salazinic acid, stictic acid and norstictic acid.
Parmelia molliuscula : Used by natives in Canadian Rocky Mountains as a narcotic.
Parmelia Cirrhata : Used in India to produce the drug 'chharila', an Ayurvedic aphrodisiac, analgesic; calmative.
Parmelia Furfuracea : 0.63% methyl-ß-orcinolcarboxylate & atranorin and 1.13% 5-chloroatranorin.
Parmotrema menyamyaense : Known as rock blooms and sold in many ethnobotanical shops.
Said to be psychoactive and to increase the potency of psychedelics.
Collema Family : The family with the fabled Icelandic hallucinogenic lichen?
In Collema flaccidum and Collema fuscovirens, insignificant small amounts of bufotenine and 5-Hydroxy-N-methyltryptamine have been found, at top respectively 14.2 μg (0.0000142%) and 18.3 μg per 100 g (0.0000183%). Collema cristatum and Collema callopismum were devoid of these alkaloids, but had some tryptophan, tryptamine and serotonin.
The fact that the enzymes for bufotenine and other tryptamines synthesis are present may mean that other species in this family, or special growing conditions, produce high enough quantities for it to be active.
Dictyonema family : An unidentified species of this family, possibly Dictyonema sericeum, is used in an infusion by the Huaorani of the Amazon jungle of Ecuador. Reported to cause intense hallucinations, supposedly used for malevolent shamanism, and to cause sterility (!). Could be typical western fear for indigenous people and their culture.
Nephroma articum : An infusion of this lichen is used in Alaska and West Canada to give strength to someone in a weakened state.
Lobaria Pulmonaria : Used to increase appetite, combat asthma, and as anti-inflammatory.
Reports of highly intoxicating beer brewed with this lichen from Siberia and Russia.
Contains stictic acid, desmethyl stictic acid, gyrophoric acid, tenuiorin, constictic acid, norstictic acid, peristictic acid, and methylnorstictic acid.
Gymnocolea Inflata :Traditionally used as a vomit-inducing drug. One secondary source says it is active as a hallucinogen.
Contains the bitter diterpenoid gymnocolin A, which causes vomiting. May be hallucinogenic, like salvinorin A.
Radula family : 172 species covering next to all areas with moderate humidity and moderate to subarctic temperatures.
At least three species contains the cannabinoid perrottetinene and related substances.
Radula marginata : Found to contain 0.56% of the cannabinoid perrottetinene and 0.087% of perrottetinenic acid, with unknown potency at cannabinoid receptors.
Said to be active, but not very potent.
Endemic to New Zealand.
Radula Perrottetii : Also contains perrottetinene.
Endemic to Japan.
Radula laxiramea : Also contains perrottetinene.
Endemic to Middle America.
Lycopodium clavatum : Contains 0.1-0.2% alkaloids, lycopodin and many relatives.
Active, likely acetylcholinesterase inhibititor and NDMA antagonist, but may be poisonous, especially in large doses.
Used medicinally for a broad range of purposes, but not commonly used.
Désolé mais pas le temps de traduire ( i am translator est un bon traducteur )
J'ai plusieurs fois vu des arbres avec des lichen énorme , sur pas mal d'abre et a mon avis ont peut y aller avant que sa soit dangereux pour les espece . Promene toi dans une foret ....
Encore un lien intéressant :
Biologie des Lichens
Pas mal de gens les utilise pour décorer donc je pense qu'on a le " droit " de les utiliser pour notre usage personelle sans trop de souci morale .
De plus les espece qui serrait le plus vite en danger serait celle qui sont utilisée pour déco and co et non comme drogue .
