Elaterium is the juice extracted from the wild cucumber, not from its leaves or roots. Only mature cucumbers should be chosen to extract the juice, as they are able to release moisture. The collected cucumbers should be left overnight and the next day placed on a sieve over a container. Each cucumber is pierced with a needle, and the juice is pressed out using cloths and collected in another vessel. If a second batch of elaterium is needed, water can be added to the remaining cucumbers, which are then pressed again. The collected juice should be dried in the sun. The second batch, with the water evaporated, leaves a residue necessary for further use, which is then dried in a mortar, resulting in a product similar to the previously mentioned elaterium.

Some prefer to let the juice evaporate in the sun three times, collecting the residue with a brush. Others add seawater instead of fresh water and mix the dried residue with honey, then wash and dry it again to make troches. The juice itself is useful when it is white, smooth, moist, light, and has a bitter taste. Applied to a lamp, it ignites quickly, indicating its utility. However, if the juice is green, rough, and ashy, it is not useful, indicating poor quality.

Many adulterate the juice by mixing it with cucumber leaves and adding starch to make it appear white, which is beneficial for purging the stomach. Properly made elaterium can last ten years. A single obolus (a small coin) dose can purge an adult, while half an obolus can purge a child, but an overdose can be fatal. For elderly patients, it helps reduce bile and phlegm, induces vomiting, and treats insomnia when mixed with salt and given warm to drink. Dissolved in water and applied under the tongue with a feather, it induces vomiting, and if a stronger effect is needed, olive oil is added and the solution applied to the same area.

Patients undergoing treatment should not be allowed to sleep, and if they vomit excessively, they should be given cold water, porridge, vinegar, and firm foods to restrain them. For menstrual regulation, it induces abortion when mixed with milk and applied to the nose, alleviates jaundice, reduces headaches when applied externally, and treats synantisis when mixed with oil, honey, or ox bile.

The root of the garden cucumber, when two oboli are taken with honey after dinner, can induce nausea for those desiring it.
