Health is dependent on the correct balance of tissue salts, together with healthy lifestyle choices; these include: environmental air and breathing; food and drink; movement and rest; sleep and wakefulness; emotions, and elimination and retention.

There is a symbiosis between the relationship of the biochemistry of tissue salts and the law of supplying deficiencies, with that of Tibb. Tibb recognises that each tissue salt has an affinity to heat, moisture, coldness and dryness, as do tissue salts; and deficiencies are corrected by supplying the tissue salt to the body which reflects its humoral composition.
