There is a reason scent gets to you faster than thought. The olfactory bulb is one synapse from the amygdala (the brain's threat and emotion centre) and two synapses from the hippocampus, where context and memory live. No other sense has this anatomy. Sight, sound, touch, taste: they all route through the thalamus first, where the brain decides what to do with the input. Smell skips the meeting and walks straight into the boardroom.
Which means scent is not just a sense. It's a route into the nervous system. It can settle the body before the mind catches up. It can also re-open something the body had quietly closed. Both of those things, the settling and the re-opening, are where the work of healing actually happens.
