Research on psychedelic-assisted psychotherapy has shown that music affects therapeutic outcomes at a fundamental level. The development of such therapies calls for research on the use of music with consciousness-altering substances, especially in contexts informed by their traditional use. Informed by ethnographic reports, our project answers this call, investigating the phenomenology of listening to icaros (medicine songs) during ayahuasca ceremonies as reported by addiction rehabilitation patients at Peru's Centro Takiwasi. We found that icaros were therapeutically significant. They elicited experiences of healing by modulating patients' emotions and the altered state induced by ayahuasca. They helped patients feel safe while guiding them through difficult memories and emotions, and facilitating experiences of healing and learning about their addictions. Thus, similar therapies must carefully consider how they incorporate music in their protocols. We suggest further research to better understand the synergistic, therapeutic effects of music and altered states of consciousness, especially in cross-cultural environments. [ABSTRACT FROM AUTHOR]

In the Peruvian Amazon, tobacco (Nicotiana rustica) is considered a master plant and is the main curing tool of local healers. Among its several medicinal uses, we find drinking tobacco juice with the purpose of purging in order to heal on a physical, mental, and spiritual level. This specific practice is part of the addiction treatment protocol developed at Takiwasi Center. The goal of this investigation was to focus on the effects of the tobacco purge as reported by therapists at Takiwasi and to elaborate its relevance within the context of addiction treatment. In order to obtain information on this topic, we performed research fieldwork based on a participant-observation approach, and retrospective data analysis on information from interviews conducted by psychotherapists with patients. As alleged effects of the tobacco purge, therapists reported that patients experienced feelings of mental clarity with the greatest frequency (n = 80), followed by noteworthy physical effects including discomfort and intoxication (n = 63). An effect on sleep and dreams was also common (n = 36) and many found the experience directly related to addiction treatment and the desire to consume substances (n = 20). [ABSTRACT FROM AUTHOR]

The medicinal plant diet is a healing process used in traditional Amazonian medicine (TAM), and it is poorly described within the scientific literature. This work analyzes the experience of seven participants in this therapy performed at the Takiwasi Center in Peru. Semistructured interviews were performed before and after treatment, documenting participants' motivation, psychological experience, and perceived personal changes (physically, psychologically, socially, and spiritually), as well as the role played by each medicinal plant. All the interviews were recorded, transcribed, and analyzed using interpretative phenomenological analysis. Reasons to participate in the plant diet included self‐discovery, personal development, interest in plant medicine, and professional realization. The experience was perceived as intense and allowed participants to experience self‐acceptance, self‐discovery, mental balance, rest, cleansing, and connection with nature. Three months after the experience, participants felt physical changes (n = 6), psychological changes (n = 7), social changes (n = 5), and spiritual changes (n = 5). [ABSTRACT FROM AUTHOR]

Phlomis fruticosa L. and P. herba-venti are species belonging to the Lamiaceae family, which have been traditionally used to prepare tonic and digestive drinks. Multiple studies also demonstrated the inhibitory effects of P. fruticosa extracts and essential oil against oxidative/proinflammatory pathways and bacterial strains deeply involved in ulcerative colitis. Considering these findings, the present study evaluated the effects of alcoholic P. fruticosa and P. herba-venti leaf extracts in isolated rat colon challenged with Escherichia coli lipopolysaccharide (LPS), an ex vivo experimental paradigm of ulcerative colitis. In this context, we assayed colon levels of pro-oxidant and proinflammatory biomarkers, including nitrites, malondialdehyde (MDA), lactate dehydrogenase (LDH), and serotonin (5-HT). Additionally, the extracts have been tested in order to evaluate possible inhibitory effects on specific bacterial and fungal strains involved in ulcerative colitis. Alcoholic P. fruticosa and P. herba-venti extracts were able to blunt LPS-induced nitrite, MDA, 5-HT, and LDH levels in isolated rat colon. The same extracts also inhibited the growth of Pseudomonas aeruginosa, E. coli, Staphylococcus aureus, Candida albicans and Candida tropicalis. In conclusion, our findings show a potential role exerted by alcoholic P. fruticosa and P. herba-venti in managing the clinical symptoms related to ulcerative colitis. [ABSTRACT FROM AUTHOR]

The analytical study of two hot-water extracts from the mushrooms Inonotus hispidus (Bull.) P. Karst and Sparassis crispa Wulf.:Fr was performed by NMR, HPLC-PAD-MS and GC-MS. The simultaneous use of different analytical techniques highlighted the diverse classes of natural products contained in these extracts. This study describes an attempt to adapt a useful phytochemical method to the direct investigation of plant water extracts, which represent the typical traditional manner for the administration of natural remedies. The heritage concerning plant processing procedures, known as traditional pharmaceutical knowledge, could play an important role in future research on medicinal species. This kind of study could be used as an update for current and future perspectives in this research field. Copyright © 2006 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
