Caña de azúcar is sugarcane, the tall tropical grass Saccharum officinarum. Its thick stalks are full of sweet juice. That juice is the source of most of the world's table sugar.
In Latin America the cut stalk is crushed in a mill. The fresh juice is sold cold as guarapo or jugo de caña. Boiled down, it becomes panela, piloncillo, melaza (molasses) and raw sugar.
People drink it for energy and for pleasure. Folk use also covers coughs, sore throats, fevers and the liver.
Here is the honest verdict: cane is a food, not a proven medicine. Long use in a tradition is not proof that it works, and it is not proof that it is safe.
Most of what cane does in your body is simple sugar at work. Sucrose splits into glucose and fructose. That gives fast energy and raises blood sugar.
Fresh juice and panela also carry small amounts of plant polyphenols. In test-tube work these mop up free radicals. Whether that does anything useful after you drink the juice has not been shown.
In animal studies, cane polyphenols appear to slow the breakdown of starch. This has not been shown to matter in people.
Policosanol is a waxy mix taken from the cane stalk. It is sold as a cholesterol supplement.
Early Cuban trials reported clear drops in LDL cholesterol. Later trials run by other teams mostly found no benefit.
The warm, sweet drinks used for colds may soothe a sore throat. That is a comfort effect, not a cure for the infection.
Cane reaches you in several forms:
- Guarapo or jugo de caña: fresh juice, often pressed at a street stall. - Panela, piloncillo or raspadura: hard blocks of boiled-down juice. - Melaza (molasses): the thick dark syrup left after sugar is taken out.
- Raw and refined cane sugar. - Chewed stalk, sold in cut sticks. - Cane vinegar, used in cooking.
- Aguardiente and rum, made by fermenting cane. These are alcoholic drinks. - Policosanol capsules and tablets, a cane wax extract sold as a supplement.
The forms are not interchangeable. A policosanol capsule is not the same thing as a glass of guarapo.
Sugarcane came from New Guinea and South Asia. Spanish and Portuguese ships carried it to the Caribbean in the early 1500s. Plantations spread across Brazil, Cuba, Colombia and Mexico, worked largely by enslaved people.
Cane became part of daily Latin American home care. Panela dissolved in hot water with lime, known as agua de panela, was given for colds, chills and tiredness. Guarapo was drunk to restore strength after heavy work or illness.
Folk healers also used cane juice for jaundice, for the kidneys and for weak appetite. These were household customs recorded by travellers and folklorists. They describe what people did, not what was tested.
See a doctor if you notice any of these:
- Yellow skin or eyes, dark urine, or pain under your right ribs. - Fever, swollen eyelids or a swollen face in the weeks after drinking raw cane juice. - Vomiting, bloody diarrhoea or a high fever after any cane drink. - Blood sugar readings that run high, or thirst and frequent urination. - Easy bruising or bleeding while taking policosanol with a blood thinner.
Stop the product and get medical help the same day for fever with facial swelling, or for yellow skin and eyes.
Sugarcane and its products are ordinary foods everywhere, with no medical approval needed. In the United States, United Kingdom and European Union, policosanol is sold as a food supplement and is not approved as a medicine. In Cuba it has been marketed as a cholesterol medicine.
