Note: This monograph focuses on the effects of Gossypium species. The particular effects of gossypol, a constituent of Gossypium and other plant species, are reviewed in detail elsewhere and will not be discussed in detail in this monograph.
Gossypium hirsutum is a cotton species native to Central America and the Caribbean. After being domesticated in the United States, this cotton species now provides over 90% of commercial cotton worldwide.
The dried root bark of cotton contains gossypol. This compound may cause abortion-inducing effects. Gossypol may be isolated more easily from the bark. Other parts of the cotton plant have limited gossypol content.
Cotton has a history of use for breastfeeding, contraception, diarrhea, female reproduction, fever, headache, pregnancy, nausea, and various other applications.
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Early research suggests that cotton may increase the complement components (immune system activators) in breast milk. Additional research on this topic is needed.
Early research suggests cotton may improve the condition of hair. More high-quality research is needed.
An herbal combination containing cotton may improve malaria symptoms. More studies using cotton alone are needed.
* Key to grades
A: Strong scientific evidence for this use B: Good scientific evidence for this use C: Unclear scientific evidence for this use D: Fair scientific evidence for this use (it may not work) F: Strong scientific evidence against this use (it likley does not work)
Tradition / Theory
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
One teaspoon of cotton-root bark has been boiled with three cups of water for 30 minutes. One to two cups of this tea have been consumed daily. Additionally, either two grams or 10 grams of a 20% cotton decoction has been taken by mouth.
Sixty milliliters of a 40% cotton seed mixture has been taken by mouth. Root bark alcoholic extracts and 2-4-milliliter liquid extracts of cotton have been taken by mouth.
For breastfeeding, a single dose of a drink containing milk, sugar, cacao, and 20 grams of cotton seed extract has been taken by mouth.
For cosmetic uses, a formula with 1% cotton honeydew extract has been applied to the hair after shampooing.
For labor induction, 1-2 teaspoons of a cotton liquid extract has been taken by mouth.
For wound care, dry and washed cotton sheets (surgical patties) have been used during surgical operations.
Children (under 18 years old)
There is no proven safe or effective dose for cotton in children.
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Avoid with known allergy or sensitivity to Gossypium hirsutum or Gossypium herbaceum, their parts, or other members of the Malvaceae family, which includes ambrette, bala, chocolate, hibiscus, and marshmallow.
Side Effects and Warnings
Cotton is generally safe when taken by mouth in appropriate medicinal doses or in amounts normally found in foods. Cotton is generally safe when the portion contains less than 450 parts per million of free gossypol.
Cotton may increase the risk of bleeding. Caution is advised in people with bleeding disorders or those taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary.
Use cautiously as a male contraceptive agent or during surgery.
Use cautiously in people taking agents for inflammation, agents for pain relief, or agents that promote urination.
Use cautiously in people recovering from abdominal surgery, and people with kidney problems, low iron or potassium levels, or stomach or intestine disorders.
Avoid in women who are pregnant or breastfeeding.
Avoid in people with known allergy or sensitivity to Gossypium hirsutum or Gossypium herbaceum, their parts, or other members of the Malvaceae family, which includes ambrette, bala, chocolate, hibiscus, and marshmallow.
Cotton may also cause altered brain inflammation when used during surgery, cytochrome P450 enzyme activity, hemorrhages, histamine release, induction of abortion or labor, inflammation, intestinal blockage, lowered potassium levels, muscle weakness or paralysis, prevention of sperm production, promotion of menstrual flow, and stimulation of the uterus.
Pregnancy and Breastfeeding
Use cautiously in women who are breastfeeding, due to a lack of sufficient data. Cotton seeds may increase concentrations of complement component 3 and 4 (natural antibacterial agents) in the breast milk.
Avoid in women who are pregnant, as cotton-root bark and seeds, which contain gossypol, may possibly induce abortion.
Cotton may interact with agents for cancer, agents for inflammation or pain relief, agents that increase urination, agents with potassium, antibiotics, antifungals, contraceptives, and iron.
Interactions with Herbs and Dietary Supplements
Cotton may interact with antibacterials, antifungals, contraceptives, herbs and supplements for cancer, herbs and supplements for inflammation or pain relief, herbs and supplements that increase urination, herbs and supplements with potassium, and iron.
