Kelpie Urine is a known remedy for seasickness.
It was mentioned that it is the best way to regain equilibrium or balance and is used as a last resort if other cures fail.
It can be noted that Keefe threw a vial of this overboard while on a boat traveling to Ravagog with Sophie, Blur, and Lady Cadence in Nightfall due to its extremely unpleasant smell.
