We'll create fresh WordPress site with Drug Half-Life Calculator installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin allows you to add a widget to your sidebar or shortcode to a page or post that displays a simple drug half life calculator. The calculator outputs the concentration of the drug that will remain in your system over a period of time. The plugin accepts two values: half-life and dosage. You can find the half life of various drugs and medications at Drugsdb.com.
To see a live example, visit: http://www.drugsdb.com/resources/drug-half-life-calculator/
Use the shortcode [halflife]
to display it on posts or pages or add it as a sidebar widget.
