Although the Legislature of the Kingdom of Hawaii banned curing through "superstitious methods" in 1886, massage was not subject to legislation until 1945. In 1947, the Board of Massage was established to regulate lomilomi and massage. The law required practitioners to pass a written test on anatomy, physiology and massage theory. Many renowned native healers were unable or unwilling to pass the test, and thus lomilomi as restorative massage was forced underground. In 2001, the Legislature passed Act 304, amending HRS section 453, allowing native practitioners to be certified by the Hawaiian medical board, Papa Ola Lōkahi, or by the various community health centers. This law is controversial among some native practitioners, but those who are certified (but not licensed) can provide lomilomi without fear of prosecution under Hawaii state law.
