Plants as silent teachers: bridging plant biology, human physiology, and eastern traditional practices through molecular insights.
Sharma A, Pratap T, Dalal K
Summary
PubMedWhy it matters This matters because the tomatoes in your garden and the oak in your local park are running versions of the same stress-response chemistry that keeps your own body healthy — understanding how plants master resilience without a nervous system could reshape how we think about both plant care and human well-being.
Scientists are discovering that plants sense danger, warn each other, and even 'remember' past hardships — all without a brain or nervous system. The chemical signals they use to do this turn out to look a lot like signals inside our own bodies. This surprising overlap suggests plants have been quietly solving survival problems that animals and humans face too, and studying them could teach us a great deal about life itself.

Plants have no brain, yet they sense their environment, communicate with neighbors, remember stress, and adapt — using molecular tools that turn out to be surprisingly similar to those found in animal and human cells. This paper argues that studying these shared mechanisms can bridge plant biology, human physiology, and ancient Eastern wellness traditions.
Key Findings
Plants use reactive oxygen species (ROS) and calcium-based signals — molecular tools also central to human cell communication — to perceive and respond to environmental stress.
Plants exhibit forms of physiological memory, allowing them to 'remember' previous stress events and mount faster, stronger responses upon re-exposure, a phenomenon with parallels to immune priming in animals.
The molecular mechanisms underlying plant environmental perception, stress adaptation, and inter-plant communication show significant overlap with pathways described in Eastern traditional medicine and human physiology, suggesting deep evolutionary conservation.
