Final answer:
Naturalistic healers focus on biological and impersonal causes of illnesses and use treatments like herbs, massage, and surgery.
Step-by-step explanation:
Foster (1976) described two main types of healers in different cultures. When considering the characteristics congruent with practices of naturalistic practitioners, these would include: Illness is impersonal and is due to biological forces; Illness is caused by alterations in the body equilibrium; and Healing modalities include herbs, massage, and surgery. These features are indicative of a naturalistic approach which focuses on natural explanations for illness and utilises methods such as herbs and surgery that are rooted in the physical realm rather than the supernatural.
