Psychedelics were used in the treatment of psychiatric conditions prior to their prohibition in the late 1960s. In the past three decades, there is a revived research interest in the therapeutic potential of psychedelic drugs with expected FDA approvals for treatment of various conditions. Given the exponential scientific growth of this field, we sought to c...
Psychedelics are used for various pathologies of the central nervous system and are currently the subject of much research, some of which relates to the compounds contained in various -type hallucinogenic mushrooms. It is difficult, however, to obtain and purify sufficient quantities of these compounds from fungi to carry out biological studies, hence the ne...
Background: Psilocybin has been suggested as a novel, rapid-acting treatment for depression. Two consecutive doses have been shown to markedly decrease symptom severity in an open-label setting or when compared to a waiting list group. To date, to our knowledge, no other trial compared a single, moderate dose of psilocybin to a placebo condition. Methods: In...
Chinese Cordyceps is a valuable source of natural products with various therapeutic effects. It is rich in various active components, of which adenosine, cordycepin and polysaccharides have been confirmed with significant immunomodulatory and antitumor functions. However, the underlying antitumor mechanism remains poorly understood. In this review, we summar...
Effects of serotonin 2A/1A receptor stimulation by psilocybin on mood and emotion processing in major depressive disorder: a randomized double-blind placebo-controlled study Major depressive disorder (MDD) is one of the world's greatest contributor to the global burden of disease and MDD affects around 17% of the Swiss population (Tomonaga et al. 2013). It i...
Background: Lysergic acid diethylamide (LSD) was extensively investigated in humans in the 1950s and 1960s. Particularly, LSD attenuated anxiety in patients with cancer. Clinical research with LSD ended in the 1970s due to regulatory restrictions but its use for personal and recreational purposes continued. In recent years, there has been a renewed interest ...
LSD (lysergic acid diethylamide) and psilocybin (the active substance in "magic mushrooms") are widely used for recreational purposes. Both substances are also increasingly used in psychiatric and psychological research to induce and investigate alterations in waking consciousness and associated brain functions (functional brain imaging, "model psychosis"). ...
Psilocybin is a classic serotonergic hallucinogen acting on the 5-HT2A receptor. It is used recreationally and in psychiatric research. Selective serotonin reuptake inhibitors (SSRIs) like escitalopram are first-line treatments for depression. They inhibit the serotonin transporter (SERT). This might cause a possible downregulation of postsynaptic 5-HT recep...
Panaeolina foenisecii is one of the most common and widely distributed lawn mushrooms in Europe and North America, and frequently involved in accidental mushroom ingestion, mainly in children. Nevertheless, there is contradictory information regarding the toxicity profile of P. foenisecii in the literature. Objective of the study was to assess clinical effec...
RationaleLysergic acid diethylamide (LSD) is used recreationally and in clinical research. Acute mystical-type experiences that are acutely induced by hallucinogens are thought to contribute to their potential therapeutic effects. However, no data have been reported on LSD-induced mystical experiences and their relationship to alterations of consciousness. A...
Most mushroom intoxications become evident within 12 hours with vomiting and diarrhea. They can be divided into incidents with a short latency (less than four hours) and incidents with a long latency (longer than four hours). As a rule of thumb amatoxin poisonings must be considered in case of symptoms appearing with a long latency (8-12-18 h), especially af...
MDMA ("Ecstasy") and its analogues such as MDE and MDA are amphetamine derivatives reported to produce an altered state with emotional overtones. Since more than ten years, ecstasy is after cannabis the most frequently used recreational drug by young adults, particularly in the so-called techno-scene. However, according to a recent survey there is an increas...
The content of tryptamine derivatives in Psilocybe semilanceata, a popular hallucinogenic mushroom, was measured by high-performance liquid chromatography. Most of the 52 samples have been collected at several localities in Switzerland during a 1-5 year period. The content of psilocybin and baeocystin varied in the range of 0.21-2.02% and 0.05-0.77%, respect...
