title: Natural products and bronchial asthma.
abstract: Two groups of naturally occurring substances, Western red cedar extracts and red tide toxin extracts, have physiologic activity on airway smooth muscle and pose either an occupational hazard in the case of Western red cedar or an exposure hazard in the case of red tide toxins. The mechanisms involved and the specific chemical entities responsible for the action of these substances remain to be fully elucidated.
