One such author is John Mirfield, who authored the Breviarium Bartholomei, in the late 14th century. The most readily available translation of his work is the volume on surgery, which would be a bit removed from my primary interest in building out an apothecary. Fortunately, Part 13 of his work covers compound drugs and describes the processes for making varies things such as syrups, electuaries, pills, powders, waters, oils, ointments and plasters. This is key information that I need for my planned projects. (Yes, I understand how to many many of these with modern methods and ideas, but to be able to view them as someone did in the 1300s? That is the very goal of all of this!)
Unfortunately, I could not find a translation of this work readily available anywhere. This section is however, contained in Popular Medicine in the Thirteenth-Century England, by Tony Hunt, in Latin. The text was pulled from a Latin copy owned by John Dee. More information on the manuscript can be found HERE. There is one additional copy of this work in existence and it can be seen in full HERE.
So what did I spend the entire day doing? Translating the first of the items - Syrups. I hope to finish the rest over the course of the next week. Items in parentheses that are headers are part of T. Hunt's categories in his book. Items in parentheses within the copy are my notes or additional information.
Of course, now that I have spent the time on this, I am sure I will find a better translation elsewhere ;-)
Of Syrups in General and Drinks
There are many syrups, electuaries, and other confections in the Antidotario of Nicholai and elsewhere, sufficiently noted by many, which I know it would be a very long occupation, as well as tedious, to insert them all here, especially since many of them are seldom compounded by physicians, but are almost always found ready at the apothecaries and pigmenters. Therefore, I will begin to say something briefly about the most important and two seemingly unknown ones, helping the master.
(General Principals)
Therefore, in the first place, there is much to be noted about the preparation of syrups
1 - One rule is that all syrup made with sugar must be boiled more than that made with honey.
2 - Another rule: every syrup must be made either with honey or with sugar.
3 - Also a rule: the less cooked all honey is, the more laxative it is, and the more cooked it is, the more nutritious it is, and the more constrictive it is.
4 - Also a rule: any syrup made with honey lasts longer than made with sugar.
5 - Likewise, the rule is that all laxatives should be boiled a little, but astringents should be boiled a lot.
6 - Another rule: no laxative should be added to the syrup except at the end of the decoction.
7 - Also, the rule: in every syrup, the decoction must be made until the consumption of half of the liquid or two parts, so that a third part remains - for otherwise it is of no use.
8 - Also: note that all the dust on the cloth must be boiled in the already clarified syrup. And in the oxymello, which is never clarified, it is placed tied in a cloth from the beginning of the decoction. (Oxymello is vinegar and honey)
Moreover, keep in mind that if you put psyllium, or dragagantum (gum-tragacanth- natural gum from the sap several species of plant originating in the Middle East) , or anything of that kind, in the syrup, it must be boiled for a long time so that the syrup seems to burn. But if you pay attention to the sign of the complete boiling of the syrup in these, it would not be valid, because at the beginning of the boiling it forms a thread due to its viscosity and also adheres to the caccia itself.
(Ingredients in Composition)
(Flowers)
If you want to make a syrup from the flowers, first boil clean water well. Then the water should be boiled and well filtered. Let it be thrown over the flowers in some vessel and the vessel be sealed. Then heat the same water again, and let it be similarly thrown over the same flowers a second time, and afterwards over others, if there are many flowers. And let this be done as long as that water has the color of flowers. Then heat this water and make a syrup from the flowers.
(Roots)
The syrup must be made from the roots as follows: The roots must first be crushed and then boiled in water or vinegar according to the requirement of the syrup. And the roots of this kind must then be boiled, and afterwards they must be removed from the fire and cooled a little, and afterwards well squeezed. And from that decoction make a syrup.
(Spices)
A syrup of aromatics [f.241rb] is made as follows: First, water and sugar are boiled. Then the powdered species should be placed in a bag with a thin line (?? ‘lineo’) and thus they should be placed in the syrup and boiled a little. And when the bag is removed, it must be well squeezed.
(Juices)
The syrup must be made from the juices in this way: The juice must be extracted and then it must be boiled in a moderate amount and then cooled. And then it is well cultivated and after it is boiled with honey or sugar until thick.
(Variety of above)
Sometimes a syrup is made from the flowers, roots, and seeds of diuretic and aromatic species. In this way, the roots must be slightly shaken and cooked well. Afterwards, the diuretic seeds should be cooked moderately. Next, they should be given flowers. And the aromatics are placed in the syrup as if it had already been made.
(Preparation)
Therefore, the instruction for making syrups should be as follows: Boil flowers or seeds or the like together with a little bit in water up to a third part. Then filter, and filter and add sugar in such a measure that to one ounce of flowers or root or powder is added one pound of sugar. And in whatever liquid you wish to make the syrup, put just enough of that liquid to cover the sugar.
(Judging the Consistency)
A sign of boiling syrup is when it is taken with a spatula and it drips continuously like oil.
Another sign is when it sticks to the spatula.
Likewise, it is another sign if a drop of boiling syrup is placed on a fingernail or a marble or a knife, if it then adheres to the finger and does not drip here or there, the syrup is cooked.
The general dose of syrup is one ounce, or so: the syrup is either much cooked or not. If, however, it is cooked a lot, two parts of water and a third of syrup must be mixed; but if it is not much cooked, half of water and half of syrup should be added. And so it should be presented. And note that all syrups must be given far from food, and with hot water in winter ('yeme' clarified as 'winter' in the Middle English Dictionary) and with cold in summer.
(Selection of ingredients)
Also, the general rule is that when any medicine is given, it must be given with a decoction of some herbs or medicines that are effective for this purpose and strengthen the patient's member. And note that if you want to make a syrup against some disease, consider in the antidote the medicine against that disease, and, with the same species crushed and boiled in water, make a syrup. Consider, however, which species should bubble a lot and which should not. For which it is necessary to know that aromatics need little cooking. Indeed, if they were boiled a lot, they would lose all their power, and for this reason such aromatics must be powdered and put in a bag. And when the syrup is clarified, then they are added.
(Clarification)
1. Furthermore, when you make a syrup from the juices and want to have a very clear one, first separate the juice and allow the bubble to settle a little. And that which seems to be starchy or has gone to the bottom, carefully remove it. And in the residue that is as clear as water make a syrup. And so it will be brighter, but not so effectively. And yet you will not be able to do this with the juice of certain cold herbs, unless it has first had an astringent power.
2. Or when this kind of juice has been boiled by itself and afterwards settles, then that which is starchy will settle at the bottom, but that which is clear will float to the top. Then strain gently through a cloth, but do not squeeze so as not to disturb the juice. And from that filtration, which appears to be like water, with the addition of sugar, a clear syrup is made.
3. If you wish to make it more clear when it has been removed from the fire, allow it to cool a little, then take five or six whites of eggs and beat them well and put them in the syrup. And then again [put] it on the fire and let it boil a little. For the albumen (protein in egg whites), by reason of its viscosity, draws with it all the impurities of the honey or of the sugar and of the herbs, and carries it by floating to the surface of the syrup. Carefully remove and deposit any impurities with a pen or the like, and if this is not sufficiently clarified, it is well cultivated again. And let the albumen be laid down as before.
4. Likewise, the clarified syrup and strained through a cloth where there are crocus and licorice powder will be more clarified and purified. And it must be known that the syrup is clarified so that it is less repulsive. And although it is clarified, it is not more effective because of this, but less. And note that it will never happen that a clear syrup is made from vinegar and sugar unless it is the purest vinegar and white sugar.
Furthermore, it should be noted that syrups, if competently prepared, can be kept for three or four years. And this should be a general rule that every time you give a syrup for digestion or division, it must always be given with warm {water}, whether it is a diuretic or not.
(Comparative virtues of sugar and honey)
Likewise, if sugar syrups are bought from apothecaries, it is to be feared that they are made from red sugar. Therefore, it is better for the doctor and the doctor to make them and buy them from the apothecaries. For red sugar is hotter than honey, and therefore honey is better than it.
But John of Saint Amando says that syrup made with honey is better than syrup made with sugar, and the reason is fourfold:
1 - First, because honey, being viscous, better preserves medicines placed in syrup than sugar, which is a rare composition.
2 - The second is because honey covers the awfulness of medicine better than sugar because honey is sweeter than anything else.
3 - The third is because honey is more purifying than sugar since honey is warm and thus common in the second step and sugar at the end.
4 - The fourth reason is that honey digests better than sugar.
But although syrup made with honey is better for digestion, yet syrup made with sugar is more effective for strengthening and cooling than with honey. But when a syrup is to be made with honey, it is necessary first to purify the new white honey very thoroughly, to which the same amount of water or of some other distilled liquid must be carefully mixed and strained, and the syrup is made. And it must boil less than a syrup made with sugar until it thickens a little.
