Gymnocladus has a keynote that tongue has blue colour, which is found in very few homeopathy medicines….

Two weeks ago a feeble farmer, aged 75, was suddenly attacked by violent stitching pains over the right hip, extending downward to the bladder. There was constant teasing to urinate, fear, extreme restless and profuse sweat with each paroxysm of pain. This condition had already lasted several days. The remedy was not very clear to my mind, but I ventured upon Aconite, which almost completely eased the pain for a number of hours after each dose, but at the end of two days it was evident that no real progress had been made, especially as a very significant new symptom-a blue tongue appeared.

Whether this blue tongue was the (problematical) effect of the four or five doses of the Aconite, or an alarming development, need not trouble us very much, but certain it is that it was the latest, and therefore the most vital, symptom. He now received one dose of Gymnocladus 6th every four hours, but after the second dose all the pain disappeared and only great weakness remained. It was either a great cure or a wonderful coincidence; he doesn’t believe the latter.

For the further study of this interesting drug, I append the following resume of its action: REGION WORSE

Nares. Cold, Walking.

Stomach. Better.

Urinary Organs Heat and rest.

Leaning on something

Peculiar numbness all over. Slow comprehension.

Head feels bound. Severe pain under eyebrows and in upper nose. Catarrhal headache. Eyes feel pushed forward. Must rub the eyes. As of flies crawling over face (r). Swelling of face; erysipelatous. Teeth very sensitive to cold (air). BLUISH TONGUE. Bread tastes dry. Livid, red fauces; sore throat. Hot, sour eructations. Burning spot in the stomach. Stitches in bowels. Aching fullness in rectum. Frequent desire to urinate. Crushing pain in left radius.
