Right until the late 18th century, animal and plant products were used as medicine, as well as human body parts and fluids. People believed, for example, that beans had a curative effect in kidney diseases, and because of their form, walnuts were used for treatments of the brain. In those days implications of natural products were mostly drawn from their form, taste or smell.
Today some companies make again use of these old mechanisms of cognition, and transfer the concept of tautological design to their products. The pharmaceutical company Merck, for example, recently developed a heartshaped tablet named „Concor“, which activates through the perception of form the implicit mental concept behind, that a heart-shaped pill is good for the heart. The shape and colour implicits in this case very obvious, the expected effect of the tablet. Because of this fact it is interesting to ask if objects, particularly for medical contexts, can be designed in such a way, that they have an impact on the healing process of the patient.
