B5 (pantothenic acid) will help reduce the severity of the histamine reaction over time, if you take it faithfully (400mg/day during allergy season), and it will help keep your lil adrenal glands from getting worn out.... and thus help prevent an overall increase in inflammatory pain that often comes along when the adrenal system is stressed.

The adrenals make the cortisol that is our bodies' natural cortisone-- which pours out to help allergies and inflammation, both, as well as keeping us vertical instead of passed-out-horizontal from physical stress.
