That's the very power it brings to the potion, but if it hasn't been dried normally, over time, the resulting potion can sometimes be unusually potent. Not reliably, unfortunately, so the dose couldn't be reduced even if a full dose wasn't needed to cover the surface of the cauldron with the simmering lacewings."
