From:  Horticultural therapy for the management of fibromyalgia: a narrative review

 Strengths and limitations of evidence for horticultural therapy in fibromyalgia.

StrengthsLimitations
Consistent direction of benefit across studiesVery small number of FM-specific studies
Improvements reported in pain, sleep, mood, and QoLMany studies have small sample sizes
HT appears safe and well-toleratedHeterogeneous interventions and outcome measures
Findings align with multidisciplinary approachLimited long-term follow-up
Some controlled and randomized studies availableFew studies include inactive control groups
Biological plausibility supported by mechanistic studiesCausality cannot be established
Potentially scalable and low-cost interventionEffect of HT often cannot be separated from exercise, socialization, or psychological support

FM: fibromyalgia; HT: horticultural therapy; QoL: quality of life.
