RESUMO
Herbal supplements (HS) are used by older persons and are often perceived as safe, although there is limited research that examines why this perception exists. A questionnaire was developed and pilot tested to investigate the use and perceived safety of HS among a convenience sample of 112 adults aged 60 to 92 in southeast Idaho. Fifty-five percent of the participants (n = 62) reported using HS in the past. Ninety-five percent (n = 59) of those using HS and 75% (n = 37) of nonusers reported they believed most or some HS were safe. Perception of herbal supplement safety was greatly influenced by family and friends, and HS users had a greater perception of safety than nonusers (p < or = .001). The top reasons for perceived safety given by HS users were that HS: (1) can be purchased without a prescription, (2) can be purchased in many locations, and (3) are natural.
