From Culpepper: It is a herb of Mars, and under the Sign Aries. It helps swimmings and giddiness in the head, or the disease called vertigo, because Aries is the House of Mars. It is an excellent remedy against yellow jaundice and other infirmities of the gall, because Mars governs choller. It strengthens the attractive faculty in man, and clarifies the blood, because the one is ruled by Mars. The continual drinking the decoction of it helps red faces, tetters and ringworm, because Mars causeth them. It helps plague-sores, boils and itch, the bitings of mad dogs and venomous beasts, all which infirmities are under Mars. Thus you see what it doth by sympathy. 'By Antypathy to other Planets: it cures the French Pox by Antypathy to Venus who governs it. It strengthens the memory and cures deafness by Antypathv to Saturn, who hath his fall in Aries which Rules the Head. It cures Quarten Agues and other diseases of Melancholy, and a dust Choller by Sympathy to Saturn, Mars being exalted in Capricorn. Also it provokes Urine, the stopping of which is usually caused by Mars or the Moon (3).


The name Cnicus comes from the Greek knekos meaning thistle, which in turn may be derived from chnizein, “to injure” referring tom the plant’s extreme prickliness (4).  Originally cultivated in monastery gardens as a medicinal herb, was once regarded as a cure-all, and in the 16th century was recommended for the plague (5).


Plant belongs to Mars. By antipathy to the influence of Venus, it strengthens the memory and, in opposition, to Saturn, cures deafness (6).
