Fissures and ulceration. Warts and horny growths on face; also on the lips.
Mouth
Paralysis of the tongue, making speech indistinct; and stuttering after excitement or vexation are the main characteristics for this area. Jahr gives a good description: ‘Distortion of the tongue, as well as the mouth, on talking; speech stammering, difficult, hissing and very badly articulated.’ In choreatic disorders, the words seem to be literally jerked out of the mouth.
This ‘awkward’ quality is also seen while chewing: tends to bite his cheek (or else his tongue) while chewing. In the proving, this was due to a swelling of the inner cheek, but clinical experience has frequently shown that the cheek biting also appears unrelated to such ‘mechanical’ causes.
On the tip of the tongue, painful bullae or vesicles appear. A typical appearance of the tongue is: both sides coated white, with a red stripe in the middle.
The buccal cavity and the tongue tend to be dry, sometimes with burning; but there may also be accumulation of water in the mouth, sometimes with a rancid taste, or much mucus collects in the mouth.
The specific action of Causticum upon the mucous membranes also manifests in a sore and burning or scraping pain, also a pain as if burnt on the tip of the tongue. A useful proving symptom in this respect is also: ‘A sore-aching spot at the palate.’ Causticum has been used, with favourable results, in the effects of erosions and burning on the mucous membranes of mouth, throat, and stomach by swallowing caustic liquids.
The taste is greasy, also putrid or sour, resembling the taste that comes from a disordered stomach.
The gums tend to swell, bleed and suppurate for a long time. Frequently recurring abscesses; also dental fistulae. Gums recede from the teeth, so that the teeth feel or actually are elongated and loose. Sensitivity of the gums (with or without toothache), making eating, chewing and biting very painful.
The teeth are also very sensitive and easily start to ache. ‘Painful teeth, driven out of their sockets.’ Cold air, or else taking cold or warm things in the mouth, produces pain, even in sound teeth. Or: chronic toothache, of a throbbing character but without heat, after a cold. ‘Nervous’ toothaches without
