Phytoncides (antibiotic plant metabolites) are thought to boost immunity in a very direct way: https://pubmed.ncbi.nlm.nih.gov/20074458/ https://pubmed.ncbi.nlm.nih.gov/20074458/ Some cultures practice „forest bathing“ which would probably reap the greatest benefits (besides living in the woods, obviously). Maybe this sounds gimmicky, but boosting immunity has a lot of downstream effects, from heart health to brain health to structural integrity and longevity. The body can put the resources it otherwise needs to do damage control into useful things like producing enzymes and correcting metabolic shortcomings.
