Ixbut

Traditionally used for: Low breast milk supply; Cough (traditional).

What is Ixbut? Ixbut is a small leafy plant from Central America. Its botanical name is Euphorbia lancifolia. Maya healers in Guatemala gave a tea of its leaves to nursing mothers who felt their milk was low. It belongs to the spurge family. Many plants in that family carry a milky sap that can sting skin and eyes. Ixbut sap is often called milder, but that has not been tested well. The honest verdict: human evidence is close to absent. A long record of traditional use shows the plant was valued. It is not proof that ixbut works, and it is not proof that it is safe. How does Ixbut work? No one has shown how ixbut acts in the body. Milk supply is driven mostly by how often milk is removed. The hormone prolactin rises when a baby feeds well and often. Any herb would have to act on top of that. Older reports from Guatemala described more milk in animals fed the plant. These reports were small and poorly recorded. They have not been repeated in good human trials. Chemists have not pinned down an active compound in ixbut. So any claim about how it works is a guess, not a finding. What forms does Ixbut come in? Ixbut is used mainly as a tea brewed from the leaves. You may also see it sold as: - loose dried leaf in Guatemalan and Mexican markets - capsules of powdered leaf - tinctures, which are alcohol extracts - mixed nursing-tea blends that list ixbut beside fennel or fenugreek Quality control is weak. The same bag may hold leaf, stem and other plants. Blends make it hard to tell which herb caused any effect or any reaction. Where it comes from: Maya healers in Guatemala used ixbut to help nursing mothers. The use was recorded in Q'eqchi' and other Maya communities. Herbalists gave a leaf tea to women whose milk seemed short. Some accounts also list the plant for coughs and for trouble conceiving. Ethnobotanists wrote about these uses from the mid-1900s onward. Ixbut still sells in local markets and in herbal shops across the region.

Helps

What does Ixbut help with? Low breast milk supply: This is the main reason people look for ixbut. Maya herbalists gave the leaf tea to mothers who felt their milk was low. The practice is well recorded in Guatemala. The evidence in people is the problem. There are no published trials that measure milk volume or infant weight gain with ixbut. Animal reports from decades ago were small and weakly recorded. Low supply usually has a cause you can find. Latch, feeding frequency, pain, thyroid trouble and heavy blood loss after birth are common ones. A lactation consultant or your doctor can check these first. Cough and chest colds (traditional use only): Some regional accounts list ixbut for coughs. This use is far less common than the milk use. No human studies test it. A cough that lasts more than three weeks, or comes with fever or blood, needs a doctor rather than a herb. Trouble conceiving (traditional use only): A few sources list ixbut for women trying to conceive. There is no human evidence for this at all. The claim rests on folk reports. This matters for safety. If you may be pregnant, do not take ixbut. Its effect on a pregnancy has never been studied.

Get urgent care for trouble breathing, face or tongue swelling, or a baby who will not wake. Rinse your eye with water for 15 minutes and seek care if sap gets in it.
