Method	Clinical Hypnosis A therapist-guided technique using relaxation, mental imagery, and suggestion to reduce hot flash frequency and severity.	Stellate Ganglion Block An injection of local anesthetic into a nerve bundle in the neck that may interrupt hot flash signals for several months.
Efficacy	Clinical Hypnosis Recommended Recommended by the Menopause Society for symptom relief. Trial average: 80% reduction in hot flash score, across the whole group (not a share of people).	Stellate Ganglion Block Recommended (limited evidence) Recommended with limited evidence by the Menopause Society.
Cost	Clinical Hypnosis Contact provider Insurance: Varies	Stellate Ganglion Block Contact provider Insurance: Varies
Duration	Clinical Hypnosis 5 weekly sessions (about 45 minutes each)	Stellate Ganglion Block One injection; effects followed for 6 months in the main trial
Reversibility	Clinical Hypnosis Reversible	Stellate Ganglion Block Reversible
STI protection	Clinical Hypnosis No	Stellate Ganglion Block No
How it works	Clinical Hypnosis Clinical hypnosis uses a deeply relaxed state, mental imagery, and suggestion, such as imagery of coolness, to reduce hot flashes. The exact mechanism is unknown; one hypothesis is that regular practice improves parasympathetic tone, part of the autonomic nervous system.	Stellate Ganglion Block A clinician injects local anesthetic into the stellate ganglion, a nerve bundle in the neck that is part of the sympathetic nervous system. This may interrupt the temperature-regulation signals that trigger hot flashes.
Prescription	Clinical Hypnosis Not required Professional Service	Stellate Ganglion Block Required In-Person Procedure
Side effects	Clinical Hypnosis None reported in trials	Stellate Ganglion Block Drooping eyelid (Horner's syndrome, temporary) Temporary hoarseness Dizziness Rare serious complications (seizure if injected into a blood vessel, bleeding)
Who shouldn't use this	Clinical Hypnosis None reported	Stellate Ganglion Block Active local or systemic infection Bleeding disorder Allergy to local anesthetic
