One homeopathic 'flu remedy, Oscillococcinum, starts with duck's liver. The liver mixture is diluted to the ratio of one part in 10400. (That's 1 followed by 400 zeros.) At that rate, one duck is easily enough to make enough anti-'flu "medicine" to satisfy the world's population many times over; in fact it's so dilute that if you were to prepare the product with only one molecule of the duck liver, it would produce more than enough 'flu potion to fill the known universe. This product reaps $20 million each year. (The unlucky duck has been dubbed "The Twenty Million Dollar Duck.")
