People who have never used psychedelics express mixed views about their use in mental health treatment, acknowledging potential benefits but also voicing concerns about safety and control. Interviews with eight participants recruited through snowball and convenience sampling revealed four themes: Imbalance within Control Dynamics, Therapeutic Efficacy, Across Generations and Borders, and Growing Awareness. Age and culture appear to shape these perceptions. While participants recognize that psychedelics could help treat mental health conditions, they remain apprehensive about their application in controlled settings.

The concentration of psychoactive alkaloids in ayahuasca tea—N,N-dimethyltryptamine (DMT), harmaline, harmine, and tetrahydroharmine—varies with the environment where the plants are grown and with how the plants are dried before brewing. Drying Psychotria viridis leaves at 43°C and Banisteriopsis caapi stems at 45°C in a forced-circulation oven best preserved alkaloid content. Neither fresh nor dried plant preparations showed cytotoxic effects on human keratinocyte cells in vitro.

Yogic practices described in the Haṭha Yoga Pradīpikā, such as Prāṇāyāma, Mudrā, Bandha, and Meditation, enhance attentional control, autonomic regulation, and neural integration. These practices parallel neuroscientific findings including vagal modulation through breathing, reduced default mode network activity, and increased gamma synchrony during meditation. Yogic descriptions of heightened intuition and expanded cognition show similarities with phenomena discussed in parapsychology, though these remain debated. Emerging models like predictive processing provide tentative explanations for such experiences. The review highlights significant conceptual overlaps across traditions, suggesting that improved attention and autonomic stability underlie altered states of consciousness, but methodological and epistemological differences require cautious interpretation and further interdisciplinary research.

Memories of near-death experiences (NDE) and spiritual contemplative experiences (SCE) show similar brain activation patterns in delta, alpha, and gamma bands, along with frontal lobe activation, as measured by quantitative electroencephalography tomography. The Greyson Scale evaluation indicates a correlation between the attributes of NDE and SCE, such as cognitive timelessness, affective peace, transcendent oneness, and out-of-body sensations. SCE subjects exhibited statistically greater brain activation than NDE subjects. The study used QEEGt methodology, which incorporates MRI anatomical information to improve the precision of EEG source localization.
