BOISE, Idaho (AP) — Two groups of Idaho naturopaths that have continued to battle for decades over licensing failed to show any signs of patching up their differences while testifying in front of lawmakers over a proposed accrediting bill.

The Senate Health and Welfare Committee narrowly approved sending HB 181 on Monday to the Senate floor. The legislation —which creates a new naturopath licensing process in Idaho— has already squeezed passed the House.

The new bill is backed by the Idaho Chapter of the American Association of Naturopathic Physicians, but it's staunchly opposed by the Idaho Association of Naturopathic Physicians.

The two groups have waged disagreed over about training and education standards for years, particularly since the Idaho Legislature approved naturopathic licensing in 2005.
