Though describing in detail the beneficial and harmful properties of foods and plants, it is far more than a
herbal. Listing its contents organically rather than alphabetically, it sets forth the six essential elements for well-being: • sufficient food and drink in moderation, • fresh air, • alternations of activity and rest, • alternations of sleep and wakefulness, • secretions and excretions of
humours, and finally • the effects of states of mind.
Tacuinum Sanitatis says that illnesses result from imbalance of these elements. Depending on the translation, the
Tacuinum Sanitatis consists of a number of horticulture remedies for a variety of conditions and circumstances. One compilation of the
Tacuinum Sanitatis that combines the text from all four of the existing manuscripts includes forty-eight different vegetables, fruits, and clothes. Each of the sections isolates a single remedy and considers the ways that the remedy is useful, the possible consequences, methods to mitigate the consequences, and the beneficial qualities. Although the exact taxonomic classification of each plant is uncertain due to differences between manuscripts and errors during translation, the remedies described in the
Tacuinum Sanitatis can still be loosely identified. The manuscripts describe root vegetables, alliums, leafy vegetables, cucurbits, other vegetables, temperate fruits, subtropical fruits, nuts, flowers, herbs, and even clothing material. The exact identity of the plant species are not always certain, as they are often labeled with Arabic words. There are several categories of vegetables present in the various manuscripts. Root vegetables of the manuscripts include
radishes (
Rafani),
turnips (
rappe),
parsnips (
pastinace), and
carrots (also
pastinace). The
alliums represented are
onions (
cepe),
leeks (
pori), and
garlic (
alea). The
leaf vegetables included are
kale (
caules onati),
lettuce (
lactuce), and
spinach (
spinachie).
Cucumber (
cucumeres et citruli),
melon (
melones indi et palestini),
watermelon (
Melones dulces/insipidi), and
bottle gourd (
cucurbite) are present for the
Cucurbitaceae. Other vegetables include
asparagus (
sparagus),
cowpea (
faxioli), and
eggplant (
melongiana). Another main category within the manuscripts is fruits, including temperate fruits –
grape (
uve),
apple (
mala acetosa or
mala dulcis),
pear (
pira),
peach (
persica), and
cherry (
cerosa acetosa or
cerosa dulcia) – and subtropical fruits –
lemon (
citra) and
pomegranate (
granata acetosa). Other items beyond vegetables and fruits are presented as remedies for conditions, such as nuts, flowers, and herbs. These remedies include
chestnut (
castanee),
hazelnut (
avelane),
rose (
roxe),
lily (
lilia),
violet (
viole),
sage (
salvia),
marjoram (
maiorana), and
dill (
aneti). However, the above examples are not a comprehensive list of every remedy included in all of the manuscript editions—some of these items are included in multiple manuscripts, whereas others are missing or additional remedies included. Within each entry of a remedy, a few qualities and uses are explained. The optimal state of the plant for medicinal use is described, such as the quality of the plant leaves. The entries include not only the benefits from the item, but also the potential dangers from using the remedy, similar to a list of side effects from modern medicine. However, the dangers described can be mitigated by a neutralizing element that is also included. Additionally, there is also typically an image corresponding to the item that is prescribed. The detailed images that accompany each remedy typically offer skewed depictions of the agricultural process, including placing too much emphasis on plant size and production, although these drawings exhibit better quality depictions of agriculture than similar images from that time. Many of the images depict people in the process of harvesting the crop instead of administering the remedy from the plant. Thus, there is a degree to which horticulture is also presented alongside the medicinal qualities of plants, however, the quality of the depictions can make identifying the species difficult. ==Notes==
