“Hexe’s themes are health, banishing and magic. Her symbols are healing, herbs and charms. This ancient Germanic witch’s Goddess rules over health, banishing curses, and teaching people the effective use of spells, charms, and other mystical procedures for improving well-being. Thus we come by the old phrase ‘hex doctor’.
Living in the 1100s, Saint Hildegard was a renowned Benedictine nun living in Bingen and ministering to people with herbal preparations received in visions. Many of these had magical overtones, perhaps by Hexe’s influence. In any case today’s theme is learning the art of weaving ‘Hexes’ for physical, mental and spiritual health.
On the physical level, take a natural object like a cut potato and rub it against an inflicted area. Bury the potato to ‘bury’ the malady and decompose it. Or carry a jet stone to absorb the problem, then cleanse the rock in saltwater to wash the bad energy away.
For mental well-being, enjoy a soothing cup of mint tea stirred counter clockwise so tensions and negativity will wane. Or, carry a fluorite stone with you throughout the day to strengthen your mental powers.
For spiritual health, sprinkle nutmeg-laden water clockwise throughout your aura to empower your psychic self. Or, carry a lapis or amethyst stone to draw Goddess-centered thinking and action into your day.”

I couldn’t find anything specifically on a Goddesses named “Hexe”. According to Kerr Cuhulain, “The English word ‘hex’ actually comes from the Greek ‘hexe’ (a female sorcerer) or ‘hexer’ (a male sorcerer). This in turn is the source of similar words with the same meaning such as the Anglo Saxon word ‘haegtesse’ and the modern German word for a witch, ‘hexe.'” 
The word hexe is also related or similar to the word hag. Wikipedia states, “A hag is a wizened old woman, or a kind of fairy or Goddess having the appearance of such a woman, often found in folklore and children’s tales such as Hansel and Gretel. Hags are often seen as malevolent, but may also be one of the chosen forms of shapeshifting deities, such as the Morrígan or Badb, who are seen as neither wholly beneficent nor malevolent. The term appears in Middle English, and was a shortening of hægtesse, an Old English term for witch, similarly the Dutch heks and German hexe are also shortenings, of the Middle Dutch haghetisse and Old High German hagzusa respectively. All these words derive from the Proto-Germanic *hagatusjon which is of unknown origin, however the first element may be related to the word “hedge”. As a stock character in fairy or folk tale, the hag shares characteristics with the crone, and the two words are sometimes used as if interchangeable.”  (Though we know better, don’t we?)
