Dongoyaro, commonly known as the neem tree, is a familiar sight in many parts of Nigeria.
Its leaves have been used in traditional medicine for generations, with people turning to them for various health and skin care purposes.
The tree, scientifically known as Azadirachta indica, is valued for its bitter leaves, seeds, bark and other parts, which contain natural compounds that researchers continue to study.
Although dongoyaro has a long history of traditional use, it is important to distinguish between its potential health benefits and effects that have been firmly established by scientific research.
Here are some of the possible benefits of dongoyaro leaves and what to know before using them.
1. May help support skin health
Dongoyaro leaves are traditionally used in skin care because they contain compounds with antimicrobial and anti-inflammatory properties observed in laboratory studies.
Neem-based preparations are sometimes used in traditional remedies for itching, minor skin irritation and other skin concerns.
However, laboratory findings do not necessarily mean that applying neem leaves directly to the skin will treat an infection or skin condition.
Fresh leaves and homemade mixtures can also cause irritation or allergic reactions in some people.
Anyone experiencing persistent rashes, painful swelling or a worsening skin condition should seek medical advice.
2. Contains antioxidant compounds
Neem leaves contain plant compounds, including flavonoids and other polyphenols, that have demonstrated antioxidant activity in laboratory research. Antioxidants help protect cells against damage caused by unstable molecules known as free radicals.
A diet containing a variety of fruits, vegetables and other plant foods can help provide antioxidants.
However, there is not enough reliable human evidence to conclude that drinking dongoyaro leaf preparations prevents diseases associated with oxidative stress.
3. May have antimicrobial properties
One of the reasons neem has attracted scientific interest is its potential to act against certain bacteria and fungi.
Extracts from different parts of the neem tree have shown antimicrobial activity in laboratory studies.
This has encouraged further research into possible uses in oral care, skin care and other health applications. Nevertheless, the strength of these effects depends on how the extract is prepared and the microorganism being studied.
Dongoyaro leaves should not replace prescribed antibiotics, antifungal medicines or professional treatment for infections.
4. May support oral hygiene
Neem has a history of use in traditional oral hygiene, particularly through chewing sticks made from parts of the tree. Some neem-based oral care products have also been investigated for their effects on plaque and gum health.
These findings are promising, but evidence for the effectiveness and safety of homemade dongoyaro leaf preparations remains limited. Brushing twice daily with fluoride toothpaste, cleaning between the teeth and attending regular dental checkups remain important for maintaining oral health.
5. May have anti-inflammatory properties
Certain compounds found in neem have demonstrated anti-inflammatory effects in laboratory and animal studies. Inflammation is part of the body’s natural response to injury and infection, but prolonged or excessive inflammation can contribute to various health problems.
