You’re still missing the point Mr t. Your link above makes no mention of the springs at Bath being dedicated to Minerva in her manifestation as a goddess of healing. In fact the opening paragraph reads -

In localised Celtic polytheism practised in Britain, Sulis was a deity worshiped at the thermal spring of Bath (now in Somerset). She was worshipped by the Romano-British as Sulis Minerva, whose votive objects and inscribed lead tablets suggest that she was conceived of both as a nourishing, life-giving mother goddess and as an effective agent of curses wished by her votaries.

No mention of healing in that paragraph or anywhere else in your link. Interestingly though there is mention that -

At Bath, the Roman temple is dedicated to Sulis Minerva, as the primary deity of the temple spa. Through the Roman Minerva syncresis, later mythographers have inferred that Sulis was also a goddess of wisdom and decisions.

Note ‘goddess of wisdom and decisions’. Again, no reference in your link to healing, or the Bath springs being dedicated to Minerva in her manifestation as a healing deity there...
