Many new mothers search for “Nchanwu and breastfeeding” because nchanwu, also known as scent leaf or African basil, is traditionally used in parts of Nigeria and West Africa as a food ingredient and herbal remedy. Some women also hear that drinking or eating nchanwu may help increase breast milk.
But is nchanwu actually safe while breastfeeding? Can it increase milk supply? And should a breastfeeding mother take it as a tea, extract or herbal preparation?
The short answer is that nchanwu used as an ordinary food ingredient is different from taking concentrated nchanwu preparations for medicinal purposes. There is also not enough high-quality human evidence to say that nchanwu reliably increases breast milk production.
Nchanwu is commonly identified botanically as Ocimum gratissimum. It is also called African basil or scent leaf. In Nigeria, the plant is known by different local names, including nchanwu or nehonwu in Igbo. It is widely used as a culinary herb.
For breastfeeding mothers, the most important issue is not whether nchanwu is “natural,” but how much is being consumed, how it is prepared and why it is being taken.
What Is Nchanwu?
Nchanwu is the Nigerian name commonly used for Ocimum gratissimum, a fragrant herb belonging to the basil family.
The leaves are frequently used in cooking because of their distinctive aroma and flavour. In traditional medicine, different preparations of the plant have also been used for various purposes.
Scientific reviews have identified several naturally occurring plant compounds in Ocimum gratissimum, and laboratory research has investigated possible antimicrobial, antioxidant, anti-inflammatory and other biological activities. However, laboratory or animal findings should not automatically be interpreted as proven health benefits in breastfeeding women.
This distinction is particularly important for mothers who are breastfeeding because a substance consumed by the mother may potentially affect the infant through breast milk, depending on its chemical properties, dose and how much reaches the mother's bloodstream.
Is Nchanwu Safe During Breastfeeding?
There is limited direct research on the safety of medicinal amounts of nchanwu during breastfeeding.
This means it would be inappropriate to describe concentrated nchanwu preparations as definitely safe or definitely dangerous without considering the preparation and individual circumstances.
A useful distinction is between food use and medicinal use.
Using a small amount of fresh nchanwu leaves as a normal cooking ingredient is very different from drinking large quantities of concentrated leaf juice, taking an herbal extract, consuming capsules or using nchanwu essential oil.
General breastfeeding guidance recommends caution with herbal remedies because safety information for many herbs is limited. The NHS, for example, advises breastfeeding mothers to speak with a healthcare professional before using herbal remedies because there may not be enough evidence to guarantee their safety during breastfeeding.
The American Academy of Pediatrics also notes that relatively little research is available for many herbal products used while breastfeeding and recommends discussing their use with a healthcare professional.
Therefore, food-level use of nchanwu and medicinal-dose use should not be treated as the same thing.
Can Nchanwu Increase Breast Milk?
One of the most common reasons people search for nchanwu and breastfeeding is the belief that nchanwu can increase breast milk production.
There is some traditional and ethnobotanical support for the idea that Ocimum gratissimum has been used as a galactagogue, meaning a substance believed to increase breast milk. Some traditional medicine literature lists the plant as a lactagogue.
There are also animal studies in which Ocimum gratissimum has been investigated in relation to lactation and offspring growth. However, animal research cannot establish that the same effect occurs in breastfeeding humans. One animal study, for example, reported observations involving offspring of treated rats but also found toxicity at a high dose.
This is why it is important not to turn traditional use into a medical promise.
At present, there is not strong clinical evidence showing that eating or drinking nchanwu reliably increases breast milk supply in breastfeeding women.
That does not prove that nchanwu has no effect. It simply means that the evidence is not strong enough to recommend it as a proven milk-boosting treatment.
Nchanwu and Low Breast Milk Supply
If a mother believes she has low breast milk supply, reaching for an herbal remedy should not be the first step.
Milk production can be affected by several factors, including how frequently the baby feeds, whether the baby is latching effectively, whether milk is being removed efficiently, maternal or infant health problems, and certain medications or hormonal conditions.
Professional breastfeeding guidance recommends assessing the underlying reason for low supply rather than immediately relying on herbal galactagogues. The American College of Obstetricians and Gynecologists states that herbal galactagogues should not be considered first-line treatment because evidence for their effectiveness is inconclusive and these substances can have adverse effects.
This is an important point for mothers who are searching for nchanwu for increasing breast milk.
Instead of assuming that low milk supply is caused by a lack of a particular herb, it is better to determine whether the baby is transferring milk effectively and whether feeding or pumping practices need adjustment.
Is Nchanwu Tea Safe While Breastfeeding?
Nchanwu tea deserves more caution than using a few leaves in food.
When leaves are brewed as tea, a person may consume a larger quantity of plant compounds than they would normally get from a meal. The strength of the tea can also vary considerably.
There is currently not enough reliable human evidence to establish a standard breastfeeding dose of nchanwu tea or to confirm exactly how its active compounds behave in breast milk.
For that reason, breastfeeding mothers should avoid treating concentrated nchanwu tea as a proven lactation supplement.
The same principle applies to homemade preparations made from large quantities of fresh leaves. “Natural” does not automatically mean that a concentrated preparation is safe for a nursing mother or her baby.
What About Nchanwu Leaf Juice?
Some traditional practices involve blending or squeezing fresh nchanwu leaves to make a concentrated drink.
This is different from eating nchanwu in normal meals.
A homemade herbal juice can have an unpredictable concentration because the amount of plant material, water and preparation method may vary. It may also introduce additional concerns related to hygiene, contamination and the use of other herbs in the same mixture.
For breastfeeding mothers, this makes concentrated leaf juice less straightforward to evaluate than ordinary culinary use.
If a mother wants to use nchanwu medicinally, particularly every day or in large quantities, it is sensible to discuss it with a doctor, pharmacist, midwife or qualified lactation professional first.
What About Nchanwu and Breast Milk Quality?
There is no good evidence showing that consuming nchanwu improves the nutritional quality of human breast milk.
Breast milk is already a highly specialized source of nutrition for infants, and its composition naturally changes according to several biological factors.
Although a mother's overall diet matters for her health and can influence some components of breast milk, there is no established evidence that nchanwu specifically makes breast milk “richer,” “thicker” or more nutritious for the baby.
Claims that a particular herb can dramatically improve breast milk should therefore be treated carefully unless supported by well-designed human research.
Can a Breastfeeding Mother Eat Nchanwu in Food?
For many mothers, this is the most practical question.
Nchanwu is commonly eaten as a culinary herb. Using a modest amount as part of a normal meal is fundamentally different from taking a concentrated extract or herbal supplement.
The available evidence does not establish that ordinary culinary use of nchanwu is harmful during breastfeeding. However, direct research on Ocimum gratissimum in nursing mothers and infants is limited, so it would be excessive to claim that every form and quantity is proven safe.
A sensible approach is food use in normal amounts rather than medicinal doses, especially when there is no specific medical reason to consume a concentrated preparation.
Mothers should also watch the baby for anything unusual after introducing a new herbal product. If a baby develops symptoms such as persistent vomiting, diarrhoea, unusual sleepiness, breathing difficulty or an apparent allergic reaction, seek medical advice promptly.
Nchanwu, Scent Leaf and Essential Oil: Are They the Same?
No. This is an important distinction.
Fresh nchanwu leaves used in cooking are not equivalent to nchanwu essential oil.
Essential oils are highly concentrated. A relatively small amount may contain much higher concentrations of plant chemicals than ordinary food portions.
Because breastfeeding safety data for concentrated Ocimum gratissimum preparations are limited, nursing mothers should not assume that an essential oil is safe simply because the fresh leaves are traditionally eaten.
Do not take nchanwu essential oil orally for the purpose of increasing breast milk unless a qualified healthcare professional specifically recommends it.
What Should You Do If Your Milk Supply Seems Low?
If you are worried that your baby is not getting enough milk, focus first on effective milk removal and professional assessment.
Useful steps may include:
Breastfeed frequently and respond to your baby's feeding cues.
Check that the baby is properly positioned and latched.
Make sure feeds are effective rather than focusing only on how long the baby stays at the breast.
Consider expressing milk when advised by a healthcare professional.
Monitor your baby's growth and other signs of adequate feeding.
Speak with a doctor, midwife, pharmacist or lactation professional if concerns continue.
A breastfeeding professional can help identify problems with positioning, latch or milk transfer and determine whether there is a genuine supply problem.
This is generally more useful than trying several herbal products at once.
Nchanwu and Breastfeeding: What Does the Evidence Really Say?
The evidence can be summarized simply:
Nchanwu is a traditional food and medicinal plant, but its role in breastfeeding has not been adequately studied in humans.
Traditional use suggests that Ocimum gratissimum has been used as a lactation-supporting herb. Some animal and laboratory research provides reasons for further investigation. However, these findings do not establish that nchanwu increases breast milk production in breastfeeding women.
There is also insufficient information to confidently determine the safety of concentrated nchanwu preparations for nursing mothers and their babies.
This is consistent with the broader problem of herbal lactation products. Even herbs that are widely used may have limited clinical evidence, and herbal products can vary in strength and composition.
LactMed, a database maintained by the U.S. National Library of Medicine, emphasizes the importance of examining available evidence when assessing substances used during lactation. For some herbs, there simply are not enough data on breast milk levels or infant safety.
Frequently Asked Questions About Nchanwu and Breastfeeding
Can I eat nchanwu while breastfeeding?
Nchanwu is commonly used as a food herb. Using a modest amount in normal meals is different from taking concentrated medicinal preparations. If you plan to consume large amounts or use an extract, discuss it with a healthcare professional first.
Does nchanwu increase breast milk?
There is traditional use of Ocimum gratissimum as a lactation-supporting herb, but there is not enough high-quality human evidence to confirm that nchanwu increases breast milk production.
Can I drink nchanwu tea while breastfeeding?
There is not enough research to establish a standard safe medicinal dose of nchanwu tea during breastfeeding. Regular or concentrated use should therefore be discussed with a healthcare professional.
Is nchanwu the same as scent leaf?
Yes. In Nigerian usage, nchanwu commonly refers to Ocimum gratissimum, which is also known as scent leaf or African basil.
Can nchanwu replace breastfeeding support?
No. If you are experiencing low milk supply, an herbal remedy should not replace an assessment of feeding technique, latch, milk transfer and possible medical causes.
Should I use nchanwu capsules to increase breast milk?
It is better not to self-prescribe concentrated nchanwu supplements for lactation. The safety, dosage and effectiveness of such preparations during breastfeeding have not been adequately established.
Final Takeaway
The search for nchanwu and breastfeeding is understandable, particularly among mothers who are looking for natural ways to support their health or increase breast milk.
Nchanwu, or Ocimum gratissimum, has a long history as a culinary and traditional medicinal herb. However, traditional use is not the same as proven clinical effectiveness.
There is currently insufficient high-quality human evidence to confirm that nchanwu increases breast milk production. There is also limited information about the safety of concentrated nchanwu preparations during breastfeeding.
For most nursing mothers, the safest practical distinction is between ordinary food use and medicinal use. Using nchanwu as a normal cooking ingredient is not the same as drinking concentrated leaf juice, taking supplements or consuming essential oil.
If you are concerned about your milk supply, speak with a qualified healthcare professional or breastfeeding specialist before relying on herbal remedies. Addressing latch, feeding frequency, milk transfer and possible medical causes is usually more important than finding a particular herb.
In short: nchanwu may be a familiar and useful culinary herb, but it should not currently be promoted as a proven breast-milk booster, and concentrated medicinal preparations deserve caution during breastfeeding.
