The basic sensation in plant states is that of sensitivity, and each plant family has its own peculiar sensitivity. Sensitivity and reactivity are vital to patients needing plant remedies.

In plant patients, things affect them, they are not able to take this or that. Some typical examples 'His screaming affects me' or 'The damp weather affects me ... the smell ... the light'. So it is not the other person per se who affects them but that particular phenomenon, for example the screaming, that affects them.

When we assume the sensation in a case is clear ... we confirm it by examining the reaction. Once both are clear, we can be sure of the family.

And this is known only when you reach the core of the case.

There is usually one specific sensation and its oposite, which is constant, and is found in all spheres of their life.
