Hebrew U. develops psoriasis ointment

The new ointment, which will be known commercially as Silkis, has been proven in clinical trials to "wipe out" the patches and scales in three to six weeks of use; if the condition recurs, treatment for a day or two relieves it again.

The new ointment is derived from a generic drug prescribed for osteoporosis and other conditions, called calcitriol, developed some 30 years ago.
