Nothing is as dangerous as a dragon, except that is a dragon with gastrointestinal issues. They are extremely agitated and prone to lashing out in pain, even during a good conversation about the rise and fall of the Allegarn Empire. It is during these times, that a dragon must empty its gizzard of the various random items it has eaten over the years, along with those contents comes extremely toxic bile.  The bile is extremely foul-smelling and slightly corrosive.  When it is exposed to air the bile begins to lose its potency, thus one must act quickly to seal it from such exposure.  Over the years I have developed a few friendships with dragons.
 
Since then I have helped develop a tonic that helps ease the pain during these times.  Since then I have been able to be there, during the times when the incident takes place. It allows my apprentices to begin the process of extracting the toxins and purifying them as soon as it happens. Corked and sealed in a vial, to preserve its potency. Sufficient for all magical potions, magical studies, and spell components.
