Essence.
This is the moisture that sticks to the fur and beard of grazing goats when they eat a plant called cystus. Dew falls on these plants and dampness accumulates, and mixed with the dew is dirt that covers the leaves of these plants. When the goat's hair is mixed with dirt and the dirt sticks to it, it is removed; this is incense.
The purest incense is the one that sticks to the beard of goats and clings to the wool located high above the ground, and the bad one is the one that sticks to the hooves and is trampled into the sand and into the ground.
Choice.
The best incense is fatty, heavy, Cypriot incense that smells good. It is yellowish, free of sand and completely dissolves in oil, leaving no sediment. And the black one, which looks like a car, is not good.
Nature.
Hot at the end of the first degree, dry at the second; incense, which is found in southern countries, is hotter. The Khuzistani says that it is cold and astringent, but it is not so.
Properties.
The incense is very thin and slightly astringent. It promotes the ripening of thick and viscous juices and moderately dissolves them. It has an attractive force that warms and opens the mouths of blood vessels. Frankincense is included in medications to soothe pain.
Cosmetics.
Frankincense promotes hair growth, makes it thick and abundant and preserves it, especially with myrtle oil and wine. It became this way only because it is rarefied, as a result of which it penetrates deeply, dissolves juices and cleanses of rot that eats away the meat. It stretches strongly and therefore attracts matter suitable for the formation of hair.
However, incense can only help at the beginning of baldness, and with hair loss and climbing out, but is not able to cure the “fox” disease, because the matter of the “fox” disease is dissolved only by a force that exceeds the dissolving force of incense, more penetrating and less astringent than the force incense
Wounds and ulcers.
Kataganis says that incense heals difficult-to-heal wounds.
Organs of the head.
Frankincense with rose oil is applied to the sore ear; it is used in the treatment of headaches as well as throbbing pain.
Respiratory and chest organs.
Frankincense helps with cough.
Eruption organs.
Incense, administered in candles, resolves uterine tumors, and when fumigated through a funnel, it expels dead fetus and afterbirth. If you drink old wine, it closes the stomach and drives urine away.
