Reading note: These are curation notes anchored to linked sources, not a clinical recommendation or protocol.

Targets / mechanism

• PDE5 expression
• aromatase inhibition
• nitric oxide production

Optimization domains

• libido
• erectile quality
• botanical
• sexual health

Research basis

• In vitro work reports reduced PDE5 expression, aromatase inhibition, and nitric-oxide effects for damiana preparations or constituents.
• Good example of a libido botanical where mechanism exists but human outcome data are still thin.

Limits, risks, and missing evidence

• In vitro PDE5/aromatase findings do not establish human erectile or libido benefit.
• Extract standardization and endocrine interaction risk require more detail.

Risk flags

• in vitro only
• extract standardization
• endocrine interactions
• limited human data
