SECT. LVI.—OF THE REGIMEN OF PERSONS ON BOARD SHIP.
With regard to the vomitings which occur to people at sea, it is neither easy nor expedient to contend with those which happen first; for, upon the whole, they are generally beneficial. After vomiting, one ought not to partake of much nor of ordinary food, but either lentils, dried and boiled with a small quantity of pennyroyal, or bread pounded in a weak and fragrant wine. One ought also to use but little drink, and that containing a weak watery wine, or vinegar with honey. The lentils ought to be first boiled, and then when they become soft, to be triturated, and afterwards dried and put into an earthen vessel. When severe vomiting lasts for a long time, one should resolutely abstain from all kinds of food, and take only a little drink, which ought to be vinegar and honey with water, containing thyme infused in it, or pennyroyal water with some fine polenta, or some fragrant weak wine with fine polenta also. In order to overcome the disagreeable stench on board ships, one may smell to quinces, thyme, or pennyroyal. One ought also to look as seldom as possible upon the sea, until one has been accustomed to live in a ship. One must likewise attend, that the water which is drunk be not muddy, ill-smelled, or saltish.
Commentary. This Section likewise is taken from Oribasius (Synop. v, 33), who copies from Diocles. Similar directions are given by Rhases, Avicenna, and Haly Abbas. Haly remarks that persons on board of a ship are often infested with lice, which are engendered by want of cleanliness. For them he recommends mercury killed, with oil, the long bithwort, &c. (Pract. i, 31.) Avicenna says that, by wearing wool smeared with oil and mercury, the lice will be killed. (Cant. p. ii.)
When the vomiting is unusually severe and protracted, Rhases recommends it to be treated with anti-bilious remedies. (Ad Mansor. vi, 14, Contin. 34.)
SECT. LVII.—ON THE MEANS OF DIMINISHING OBESITY.
When the body gets to an immoderate degree of obesity, it will be necessary to melt it down and reduce it. It was mentioned formerly that the warm temperament renders the body lean, and therefore it ought to be superinduced, if possible, upon that of fat people, in order to reduce them to the proper state. You have also learned that active exercise, an attenuant regimen, medicines of the same class, and mental anxiety, bring on the dry temperament, and thereby render the body lean. What an attenuant diet consists of is perfectly obvious; but the more powerful medicines, such as the seed of rue, particularly the wild, with its tops, the round birthwort (aristolochia rotunda), the small centaury, gentian, poley, and the stronger diuretic medicines, as Macedonian parsley: all such medicines, either alone, or together, attenuate the humours, and evacuate the body. The salts also from burned vipers and the theriac attenuate the body. The body may also be reduced and attenuated, by having an oil rubbed into it, containing the root of the wild cucumber, marshmallows, gentian, and the root of the all-heal and birthwort, or the poley and centaury. One ought not to take food immediately after the bath, but should first sleep for a little time. And it will be better if the water of the bath possess diaphoretic properties, and, more particularly, if we can have recourse to a natural one, such as that in Mitylene. If it cannot be procured, the flower of salt may be mixed with sea water. Thin white wines ought to be used. Dry rubbing with thick towels is calculated to reduce the fat. A smaller quantity of food ought to be given in proportion to the exercise taken. Insolation also is of use for obesity. Fat persons ought not to take a fragrant draught before a meal; and it will be best if they eat only once in the day. The body ought to be rubbed with nitre (soda), and the rougher salts. A large quantity of nitre in the bath is attenuant, but a small quantity only stimulates to nourishment. The following mixture is attenuant: Of pepper and Macedonian parsley, two parts, of asarabacca and anise, one half. This acts well, both as a diuretic and a cathartic.
Commentary. This is taken from Oribasius. (Synops. v, 40.) Aëtius uses nearly the same words. (iv, 32.) Celsus recommends the tepid salt-water bath, hard exercise, food of an acid or austere kind, and restricted sleep. (i, 3.)
Galen gives an interesting account of the manner in which he cured a person of obesity in a very short space of time. He says, “I first made him take quick exercise, and afterwards wiped off the sweat with a linen cloth. I then rubbed his body with the volatile ointments called acopa, and after this friction I led him to the bath. I did not then give him food at once, but directed him either to rest, or to follow any occupation he was inclined for, and then repeated the bath; after which I gave him as much food, not of a very nourishing description, as he was disposed to take.” (De Sanit. tuendâ, vi, 8.)
Avicenna recommends hard exercise and frequent baths, and vinegar to drink. (i, 3, 4.) Rhases recommends fat persons to abstain from animal food, wine, milk, and all sweet things; to live upon pot-herbs, and such things as are saltish and sour; to take purgatives and diuretics, to use much hard exercise, and to remain long in the bath. (Ad Mansor. v, 61.) In another work he treats of this subject at great length. He recommends acids, and especially vinegar. In short, he agrees with Galen, that all things of a bitter, sour, and attenuant nature reduce obesity; and also that saltish things which have the property of opening the bowels do the same. Nothing, he says, tends more to reduce corpulency than frequent baths and hard friction. (Contin. iv.)
