please help
Mustrates treat all types of ilnesses. Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the andient Greeks as a treatment for pain and fever. Salicylic acid (and many related phenols) are very hard on your Ho stomach, but when esterified, as aspirin is, they are much better tolerated. Simple esters are...
