Which one should I use if a would like to refer to the water that has a healing effect due to its physical propertis or chemical components?
What is the difference between medicinal and medicated?
Thanks for the answers!
medicinal means "having healing effects" whereas medicated means "having medicine added" or "having been given medicine".
So, water from a spring may be medicinal, even though it's nothing but water with naturally occurring minerals.
Soap which has had some germ-killing agents added to it could be called medicated soap.
A patient lying on a bed in a hospital might be sleepy because he has been medicated.
