Cotton (also called American cotton, American upland cotton, Bourbon cotton, upland cotton and lu di mian), scientifically Gossypium hirsutum syn. G. jamaicense, G. lanceolatum, G. mexicanum, G. morrillii, G. palmeri, G. punctatum, G. purpurascens, G. religiosum, G. schottii, G. taitense and G. tridens, is a tender annual which can reach a height of 1.5m (5′). It requires a sunny position and rich, well-cultivated acid to neutral soil.
Some cultivars require 2-3 months dormancy before sowing. All types need a growing season of at least 180-200 days at around 21ºC (70ºF) and will not survive frost. Sow seed in Spring 2.5cm (1″) deep at a minimum temperature of 18ºC (65ºF). Cotton will be ready to pick 24-27 weeks after sowing. The seeds should be removed for medicinal use, sowing or storage. The roots should be dug up after the cotton has been collected, the bark pared off and dried for later use, and the remainder discarded.
NB: Not suitable for use by pregnant women except during labor. Only for use by professional herbal practitioners.
Make a decoction using 1 tsp dried root bark to 750ml (3 US cups, 24 fl oz) water boiled in a covered container for 30 minutes. The dosage is 250-500ml (1-2 US cups, 8-16 fl oz) per day, taken cold (sip it, don’t drink it all down in one go).
The decoction has been used by women at almost every stage of their reproductive life to induce periods (emmenagogue), for painful periods (dysmenorrhea), irregular periods, as a birthing aid (used by the Alabama and Koasati tribes to relieve labor pain), to expel the afterbirth, increase milk production (galactagogue) and for menopausal problems. Other uses include constipation, coughs, diarrhea, dysentery, nausea, urethritis, fever, gonorrhea, headache, hemorrhage and general pain relief.
It contains gossypol, which at low doses acts as a male contraceptive (see next paragraph), a fact which was discovered because Chinese peasants in Jiangxi province used cottonseed oil for cooking — and had no children.
Cotton seed cake is often used for animal fodder. However, because of the gossypol content long-term feeding may lead to poisoning and death, and will definitely reduce fertility.
Oil extracted from cotton seed is used in the manufacture of soap, margarine and cooking oil. Fuzz not removed in ginning is used in felt, upholstery, wicks, carpets, surgical cotton and for many other purposes.
Cotton aromatherapy oil is difficult to find. Don’t confuse this with ‘clean cotton’ or ‘fine cotton’ fragrance oils. Check the latin name. Even if you do find it, the uses are unknown – unless you know better (if so, please contact me).
NB: Cotton essential oil is not suitable for use by pregnant women, children under 12 years or anyone suffering from epilepsy or high blood pressure. Never use it undiluted (dilute 3 drops to 10ml carrier oil). It is a photosensitizer (makes skin sensitive to sunlight).
As I always point out, any herb intended for medicinal use including cotton should be grown organically to avoid foreign chemicals from destroying or masking the important constituents which make it work. Organic gardening is the subject of my sister site The Gardenzone, if you need help with this.
