Identity:
The keya plant usually grows to a height of about seven to eight feet. Branches grow out from the main stem.
The leaves are very long—about six to ten feet—and four to six inches wide. The edges of the leaves have sharp, saw-like spines. The leaves of the keya plant can be described as a larger version of pineapple leaves. There are two categories of keya plants: one female plant, and another variety known as Sitaketaki.
Uses:
Keya flowers, their pollen, and the roots of the plant are used to prepare medicines.
If a person is bitten by venomous insects such as hornets, wasps, or scorpions, or if poisonous saliva contacts the skin, swelling and pus may develop at the affected area. In such cases, about 20 grams of keya plant root should be ground on a stone slab, slightly warmed, and applied to the affected area. This neutralizes the poison, prevents swelling and pain, and stops the toxin from spreading to other parts of the body.
For insomnia, 50 grams of keya plant root should be lightly crushed and boiled in 500 milliliters of pure sesame oil for five to seven minutes. After allowing it to cool completely, the oil should be stored in a glass bottle with the lid tightly closed. Applying this oil to the body during bathing for several days promotes deep sleep. This oil is considered an effective remedy for insomnia.
In cases where even mild stimulation—such as viewing sexual images, reading suggestive material, or physical contact—causes a clear, saliva-like discharge from the penis, the following remedy is used: two or three outer white petals of the keya flower should be lightly crushed and soaked overnight in a steel glass of warm water. The next morning, the water should be consumed once on an empty stomach and once more later in the day, for several consecutive days. When crushing the petals, a stone slab or steel mortar and pestle must be used; iron tools are prohibited.
