"As the oil (or butter) of cocoa is very anodyne, or an easer of pain, it is excellent, taken inwardly, to cure hoarseness and to blunt the sharpness of the salts that irritate the lungs. In using it must be melted and mixed with a sufficient quantity of sugar candy and made into lozenges, which must be held in the mouth until the substance melts quite away, so that it can be swallowed gently. Taken seasonably the oil is also a wonderful antidote against corrosive poisons.
"It is the best and most natural pomatum for ladies to clear and plump the skin when it is dry, rough, or shrivelled, without making it appear either fat or shining. The Spanish women at Mexico use it very much, and it is highly esteemed by them.
"The leaving off the practice of anointing the body with oil can be attributed to nothing else but the ill smell and other disagreeable effects that attended it; but if oil of chocolate was used instead of oil of olives those inconveniences would be avoided, because it has no smell and dries entirely into the skin. Nothing certainly would be more advantageous, especially for aged persons, than to renew this custom, which has been authorized by the experience of antiquity.
"Apothecaries ought to make use of this, preferably to all others, as the basis of their balsams, because all other oils grow rancid, and this does not.
"There is nothing so proper as this to keep arms from rusting, because it contains less water than any other oil made use of for that purpose.
" In the West Indies they make use of this oil to cure the piles. Others use it to ease gout pains, applying it hot to the part, with a compress dipped in it, which they cover with a hot napkin. It may be used after the same manner for the rheumatism."
M. Arthur Mangin says : "When pure and freshly extracted cocoa-butter is of a pale yellow color; its consistency is about that of tallow. Its odor is faint, but sweet, and its taste pleasant. When thoroughly purified, and protected from heat, air, and dampness, it may be preserved, without perceptible alteration, for several years.
"It is insoluble in water, hardly soluble in alcohol, completely soluble in sulphuric ether and the essential oil of turpentine. Its density is 0.91. It softens perceptibly at 240 or 250 (Centigrade; i.e., 56 or 57 Fahrenheit), but melts only at 290, and becomes entirely liquid only at 350 to 400. It cannot boil without being decomposed.
It contains, according to M. Boussingault, carbon, .766; hydrogen, .119; oxygen, .115. Cocoa-butter formerly played a tolerably important part in medicine, by reason of the numerous properties attributed to it. It was called a pectoral, an expectorant, a humective, a demulcent, an emollient, a refrigerative, etc., etc. It was prescribed for persons suffering from or suspected of chest diseases, nervous coughs, bronchitis, etc., and it was combined with kermes, ipecacuanha, etc., to make pills, emulsions, opiates, and other remedies.
"At present it is no longer prescribed for internal use; but pharmacists, as well as perfumers, make it the basis of many pomades and ointments, whose use is, we are assured, most beneficial, and, at all events, most agreeable. Cocoa-butter, pure or simply combined with an oil which renders it more or less unctuous, is one of the smoothest, most fragrant, and, if we may be allowed the expression, most savory, pomades which can be used for the hair or skin, and it is astonishing that there should be preferred to it so many equivocal compounds whose exorbitant price is justified by not one of the properties claimed for them by the puffs of perfumers."
"This concentrated oil," says M. Del-cher, " is the best and most natural of all the pomades which ladies, who possess a too dry skin can use to make it smooth, soft, and polished, without any greasy or shining appearance, which is produced by most of the pomades advertised for the purpose.
"I agree," continues the same author, "with the opinion of M. Plisson, who advises the use of cocoa-butter pomade for women who suffer from acrid eruptions, cracked lips, breast, etc. The Spaniards of Mexico understand the value of these preparations; but, as in France, this concentrated oil hardens too much, it is necessary to mix it with the oil of the ben-nut,
or of sweet almonds. If the ancient custom of the Greeks and Romans should be revived, of anointing one's self with oil to give suppleness to the limbs and to guard against rheumatism, the oil of cocoa should be chosen for the purpose.
"Considered as food, and asa medicinal substance, cocoa-butter possesses the same fundamental property as other fat. It supplies to respiration the necessary combustible elements, and renders it, in consequence, more easy and active. It may, therefore, be administered with advantage to persons suffering from affections of the chest, and possesses the advantage, in common with only a very small number of substances of the same kind, that the most fastidious and obstinate patient may take it for the whole of his life without disgust."
