The Lacs: A Materia Medica & Repertory
A one-time add-on bringing Patricia Hatherly's definitive work on the milk remedies into Similia: 22 lac materia medicas and a dedicated repertory of over 16,000 rubrics, drawn from the provings and her clinical experience with the lac family.
The definitive work on the milk remedies
The Lacs gathers the provings, themes, clinical cases and comparative insights on the milk remedies into a single coherent reference, shaped by Patricia Hatherly's clinical work on the provings of breast milk and women's health.
22 lac materia medicas
From the well-known Lac caninum, Lac humanum and Lac maternum to Lac delphinum, Lac leoninum, Lac lupinum and rarer milks such as Lac camelum dromedarum and Lac phoca vitulina, each remedy is presented with its themes, mentals, physicals and clinical indications.
A dedicated Lacs repertory
Over 16,900 rubrics with more than 31,000 remedy additions specific to the lacs, organised in 45 sections and fully searchable in Similia alongside your other repertories — including AI semantic search.
Themes that run through the lac family
Nurture and abandonment, bonding, hierarchy and group dynamics — the core themes of the milks are traced through every remedy, making it easier to recognise when a case calls for a lac and to differentiate within the family.
