In the great words of Jackie Chan's Uncle I have a tale from a co-nurse from work whose paient had to tell her he took an ancient Chinese remedy. She was working the heart monitors and thought at one point she may need a bed next to him. She couldn't see straight while trying to draw his blood.
"I ate 2 bowls of garlic!," the patient said. "It is supposed to bring blood pressure down."
Poor guy was so proud he did it but the department found out how fast garlic fumes travel.
