Dr FORBES (BARKER, SOUTH AUSTRALIA) (Minister for Health) - I assume that the honorable member refers to the methods of treatment advocated by Mr. H. C. Ashton of Coogee and which he calls natural science. This is not a recognised method of treating heart disease. I am informed that the National Heart Foundation has not considered investigating it. The Foundation has had some correspondence with Mr. Ashton but has not got very far, because he has failed to reveal the nature of the treatment he advocates. The honorable member has asked what is the attitude of my Department. From the information available to it my Department believes that this treatment has no proper scientific foundation and, therefore, does not merit further investigation.
