“Meditrina’s theme is health. Her symbols are healing charms and herbal preparations. This Roman Goddess of healing magic specializes in the use of wines, herbs and empowered charms to restore our health when summer colds or weariness set in.
In Italy, this is a time to go to Madonna del Carmine’s church bearing an emblem of one’s sickness so the Madonna (a Goddess type) can heal the malady. We will be turning to Meditrina instead, invoking Her power to make health-provoking amulets for physical protection and healthful wine.
To make yourself a Meditrina charm that keeps health with you, place a pinch of caraway, marjoram, nutmeg and thyme in a green cloth and tie it up. Put this in sunlight (considered healthful) for several hours then bless it saying,
‘Meditrina, see my need. I am open to receive.
Throughout the day good health impart in my body, mind and heart.’
Carry this often. To change it so it protects you from sickness, use a red-colored cloth filled with apple peel, allspice berries and a pinch of cinnamon.
To make an aqua vitae (a healthful wine) that will internalize Meditrina’s well-being, begin with a base of apple juice or wine. In this, steep a cinnamon stick, cloves, ginger, allspice, nutmeg and a bit of a honeycomb. Do this during a waxing moon if possible to promote growing health, then drink it as desired.”

So, not too much on this Goddess today. She appears to be a minor Goddess of wine and health in Roman mythology. According to Wikipedia, “Meditrina was a Roman goddess who seems to have been a late Roman invention to account for the origin of Meditrinalia [which was celebrated on October 11]. The earliest account of associating the Meditrinalia with such a goddess was by 2nd century grammarian Sextus Pompeius Festus, on the basis of which she is asserted by modern sources to be the Roman goddess of health, longevity and wine, with an etymological meaning of ‘healer’ suggested by some.”
