The sense of taste depends on stimulation of organs known as the taste buds which are mostly situated in the tongue, though a few are found in the soft palate. To cause this stimulation, a substance must be in solution and the sensation it gives rise to is either sweet, sour, salt, or bitter, or a combination of these. Sweetness is best appreciated at the tip of the tongue, sourness at the sides and bitterness at the back.
The nerves connected with the taste buds carry impulses to a center in the medulla, whence they are carried up to the parts of the brain towards the tip and inner side of the temporal lobe, in close relation to the area of brain concerned with the sense of smell. Indeed, flavors which are usually thought of as being purely the result of taste sensations are really compound sensations of taste and smell.
The loss of taste, or ageusia, may occur when the tongue is too dry or its surface disordered by the presence of a copious furring or otherwise. The impairment of taste in a common cold is a reminder of the part played by smell in the discrimination of flavors. Loss of taste may also be due to disorder of the taste nerves that is in the lingual, the chorda tympani and the glossopharyngeal, being nervous connections up to and including its centers on the brain. The chorda tympani is a branch of the facial nerve and partial loss of taste may be noted in connection with facial paralysis.
Loss of taste may occur in hysteria, and in this disorder there may also be hallucinations of taste, though such may also occur in insanity and when there is a tumor in the neighborhood of the taste centers in the brain.
The hallucination may be one of the simple tastes, but it may be an unpleasant one. A bad taste is common, however, in digestive disorders and when some drags are being taken. See: Smell.
Application and treatment:
Placement of the electrode pad into the mouth must always be done with the consideration that if there are mercury amalgams present in the teeth, the mercury will tend to be leeched out, making the mouth and saliva highly toxic, and therefore should not be swallowed.
Place the negative pad in a pan in which the opposite foot is placed for best results. This procedure may be painful, if there are sores in the mouth and the output must be carefully controlled. Sessions should be immediately followed by a thorough course of detox frequencies lasting 15 to 30 minutes.
After the mouth has been washed out thoroughly there will be an unusual condition in the mouth, which is the absence of any living bacteria. The mouth will feel very clean, and if the cause of a lack of taste, as opposed to a lack of smell, has been caused by an infection, one or two repetitions of this treatment will cure it.
Although the presence of any food particles in the mouth will allow the rapid re-growth of bacteria such as those responsible for tartar, and the impaction of food into the cavities of septic teeth will quickly return to their previous septic conditions, the application of pads directly to the teeth and gums will greatly reduce the progress of most forms of advanced tooth and gum decay. However it is not to be considered an alternative to proper dental hygiene and regular dental examinations. A 50% solution of hydrogen peroxide and water will also be of help in the removal of bacteria in the mouth when used as a periodic mouth wash.
