Chakras are subtle, dynamic energy vortexes and are as much a part of our bodies as our arms and legs. You can't see electricity, but when you turn on the light, you see it's effect. The Chakras can similarly be understood by there effects. Physical Organs and maladies in the area of a chakra can be treated with stones of the colour relating to the chakra. It is not surprising that our subtle energy centres are especially connected to the physical body in their location. A basic example of this would be using green stones like chlorite or peridot to treat heart or chest conditions, as that organ is influenced by the 4th chakra, or heart chakra.

The logic is that as gross matter manifests from subtle energy, so strengthening the chakras in the problem area would be a start. Another Point, is that while the organ may be healed conventionally, if the underlying energetic imbalance is not addressed, the condition may return. A man may have a heart attack and blood thinners keep him going, but if the causes are not addressed, stress for example, there's a good chance of more heart problems.
