Which of the following statements is correct?

Choice A reason: Melatonin is a hormone that regulates the sleep-wake cycle and induces drowsiness. While it affects consciousness and is technically psychoactive, it is not classified as an herbal supplement but rather a hormone. Its psychoactivity is mild and primarily limited to sleep regulation.

Choice B reason: Tryptophan is an amino acid precursor to serotonin, which influences mood and sleep. It has psychoactive properties due to its role in serotonin synthesis, but it is not typically categorized as a standalone psychoactive herbal supplement.

Choice C reason: SAM-e (S-Adenosyl-L-methionine) is a compound involved in neurotransmitter synthesis and is used for mood disorders. It alters mental states and is considered psychoactive, but it is a synthesized supplement rather than a traditional herbal product.

Choice D reason: Valerian is a well-known herbal supplement with sedative properties. It acts on GABA receptors in the brain, promoting relaxation and drowsiness. Among the choices, it is the most classically recognized psychoactive herbal product due to its direct central nervous system effects.

The correct answer is: C

Choice A reason: Structural family therapy was developed by Salvador Minuchin, not Virginia Satir. It focuses on reorganizing family structures to improve interactions and resolve dysfunction. While influential in family therapy, it is unrelated to Satir’s work.

Choice B reason: Strategic therapy was pioneered by Jay Haley and the Milan Group. It emphasizes problem-solving and directive interventions, often using paradoxical techniques. This approach differs significantly from Satir’s emphasis on emotional expression and self-awareness.

Choice C reason: Experiential therapy, particularly the Satir Transformational Systemic Therapy (STST), was developed by Virginia Satir. Her model emphasizes emotional honesty, self-esteem, and congruent communication. She believed that change occurs through authentic emotional experiences and that individuals possess innate resources for growth. Her work laid the foundation for experiential approaches in family therapy.

Choice D reason: Solution-focused therapy was developed by Steve de Shazer and Insoo Kim Berg. It centers on identifying solutions rather than exploring problems, using brief interventions and goal-setting. This model is future-oriented and pragmatic, contrasting with Satir’s depth-oriented, emotionally expressive style.
