This cluster of papers focuses on the research and application of biofield medicine, including biofield treatment, qigong exercise, and biophoton emission. The papers explore the biophysical basis, role in medicine, and potential health benefits of biofield therapies. Additionally, they investigate the effects of external energy on various materials, the impact of biofield treatment on plant productivity, and the potential role of biophotons in neural communication. The cluster also delves into the relationship between biofield interventions and oxidative stress, as well as their effects on physical and thermal characteristics of different substances.
