The effect of ethanol as an oxidative stress factor has been indicated by the increase in cellular respiration observed in the dark and also in the light even before the activation of photosynthesis. The marked acceleration of growth of <i>G. sulphuraria</i> culture in the light is most likely due to the stimulation of respiration by ethanol with generation of CO<sub>2</sub> and its use by chloroplasts as an additional carbon substrate during the photosynthetic process.

It is hypothesized that phytohormones may be used as drugs with no side effects. One of them could be the phytohormone indolyl-3-acetic acid (IAA), which is a heteroauxin and can be synthesized by some microorganisms and animals, including mammals. This phytohormone is an important derivative of indole, which is catabolized from dietary tryptophan by the intestinal microbiota. IAA can scavenge free radicals, inhibit oxidative stress, and reduce the production of proinflammatory cytokines. As a ligand of the aryl hydrocarbon receptor, IAA can regulate intestinal homeostasis and suppress inflammatory responses. This review summarizes the current literature data on the vital role of IAA in the treatment of cancer, type 2 diabetes, rheumatoid arthritis, liver disease, Alzheimer’s disease, dental diseases, and microbial skin diseases.
