What is Christmas bush (gyama)? Christmas bush is a West African shrub whose leaves are used for loose stools, sore mouths and skin wounds. Its botanical name is Alchornea cordifolia. In Ghana it is known in Twi as gyama. The plant is a sprawling shrub of riverbanks and forest edges. Healers use the leaves most often. Root, stem bark and young shoots are also used. Here is the honest verdict. Nearly all the research sits in test tubes and in rodents. There are no good trials in people, so no benefit is proven. Long use in a tradition tells you that people valued the plant. It is not proof that it works. It is also not proof that it is safe. How does Christmas bush (gyama) work? No one has shown how this plant acts in the human body. The leaves hold a lot of tannins. Tannins are astringent, which means they make soft tissue draw tight and weep less. That is the usual reason given for the old use in diarrhoea. In test tubes, leaf extracts slow the growth of several bacteria and fungi. Some of these germs are linked to gut and skin infections. Whether this happens on a person is not established. In rodents, leaf extracts have slowed gut movement and reduced swelling. In dish tests, some extracts slow the malaria parasite. Results in dishes and animals often fail to carry over to people. The plant also holds alkaloids, which are strong plant chemicals. Their effects in people have not been mapped. That is one reason this page treats the plant with care rather than confidence. What forms does Christmas bush (gyama) come in? Most traditional use is a water brew of fresh or dried leaves. Common forms include: A leaf decoction, meaning leaves boiled in water and strained. Crushed fresh leaf laid on wounds and sores. A cooled brew used as a mouth rinse or gargle. Chewing sticks cut from the stem. Dried leaf powder, sold loose or in capsules. Tinctures and mixed herbal tonics sold online. Strength is not fixed in any of these forms. A capsule label and a home brew are not comparable. Mixed tonics raise an extra problem, since you cannot tell how much of each plant is in them. Where it comes from: Christmas bush has a long record across West and Central Africa, including Ghana, Nigeria, Cameroon and the Congo basin. Written records of its use go back to colonial-era plant surveys. Oral use is older. Healers used leaf brews for diarrhoea and dysentery, which means bloody diarrhoea. Crushed leaves were laid on wounds, boils and ulcers. Cooled brews were used as gargles for sore throats and mouth sores. Other past uses included coughs, chest pain, fevers, and complaints of the womb. In some areas it was given to bring on labour. Modern readers should not copy that use. The English name comes from the plant's red leaves and fruit late in the year.

Helps

What does Christmas bush (gyama) help with? Diarrhoea and dysentery (bloody diarrhoea): This is the main traditional use. Healers gave leaf brews to firm up stools and settle cramps. In rodents, leaf extracts slowed gut movement and reduced fluid loss. In test tubes, extracts slowed some gut bacteria. No controlled trial in people backs this up. Bloody diarrhoea, or diarrhoea with fever, needs medical care. The same goes for diarrhoea in a baby, a young child or an older adult. Fluid loss is the real danger, and a herbal brew does not replace rehydration salts. Mouth ulcers and sore throat, as a rinse: Cooled brews were used as a gargle for raw mouths and throats. Chewing sticks from the stem were used on gums. Tannins are astringent and may make a sore surface feel tighter and less raw. That effect is short and is not healing. Lab tests show the extracts slow some mouth bacteria, but this has not been tested as a mouthwash in people. A mouth sore that lasts more than two to three weeks should be looked at by a doctor or dentist. Wounds, boils and skin sores: Crushed leaf was a common dressing across the region. In rats, leaf extracts sped up wound closure in a few small studies. In dishes, extracts slow bacteria and fungi linked to skin infection. Human wound-healing trials are lacking. Plant material from the ground is not sterile. Putting it on a deep, dirty or spreading wound can make matters worse. Red streaks, swelling, pus or fever mean you need medical care, not a poultice. Coughs and chest complaints: Leaf brews were drunk for coughs, chest pain and breathlessness in several West African settings. There is very little research here. Some animal work suggests a calming effect on inflamed tissue. Nothing shows a benefit for coughs or asthma in people. A cough with blood, weight loss, night sweats or breathlessness needs a doctor. These can be signs of tuberculosis or other serious illness. Fever and malaria, in tradition only: The plant appears in many regional surveys of antimalarial remedies. In dish tests, some extracts slow the malaria parasite. That is a long way from treating a person. There is no trial showing that it clears malaria in people. Malaria can kill within days. Do not use this plant in place of a tested antimalarial drug and a blood test. Period and childbirth uses, in tradition only: Some healers used the plant for period pain, and some gave it in labour to speed delivery. That history is a warning, not a recommendation. It suggests the plant may act on the womb. No one has studied this safely in pregnant women. For this reason, pregnancy is a firm reason to avoid the plant in any form taken by mouth.

When should you see a doctor?

Stop using it and see a doctor promptly if any of these happen.

Yellow skin or eyes, dark urine, or pain under your right ribs. These can point to liver trouble.

Passing much less urine than usual, or swelling in your legs.

Diarrhoea that lasts more than two days, has blood in it, or comes with fever.

Signs of fluid loss: a dry mouth, dizziness on standing, or little urine.

A wound that turns red, swollen, hot or leaks pus.

Fever after travel in a malaria area needs same-day testing, not herbs.
