Rongoā Māori & Native Botanicals

Rongoā Māori healing plants constitute the medicinal flora of Aotearoa New Zealand, utilized within a holistic health system that addresses physical (tinana), spiritual (wairua), family (whānau), and mental (hinengaro) well-being. Central to this traditional practice are native species such as Kawakawa, Manuka, and Kumarahou, which are harvested according to strict tikanga (cultural protocols) to ensure the preservation of the plant’s mauri (life force) and the sustainability of the natural environment.

Tikanga and the Art of Sustainable Harvesting

In the realm of New Zealand multi-cultural herbalism, understanding Rongoā Māori requires more than merely identifying plant species and their biochemical properties. It necessitates a deep respect for Tikanga—the customs and protocols that govern the relationship between humans and the natural world. Rongoā is not simply the application of a leaf to a wound; it is a connection to the atua (gods) and the forest (Te Wao Nui a Tāne).

The Importance of Karakia and Mauri

Before any harvesting occurs, it is customary to offer a karakia (prayer or incantation). This is not merely a ritualistic formality but a method of focusing intent and asking permission from Tāne Mahuta (the guardian of the forest) to remove a part of his children for healing purposes. This process acknowledges the mauri, or life force, of the plant. In the professional practice of Rongoā, it is believed that if a plant is taken without respect or acknowledgment, its healing potency is diminished. For modern herbalists integrating these plants, adopting this mindset of gratitude is essential for ethical practice.

Harvesting Protocols

Sustainable harvesting is embedded in the DNA of Rongoā Māori. The rules are practical as well as spiritual, designed to ensure the longevity of the bush. Key principles include:

• Never take the ‘Grandparents’: Harvesters avoid the central shoot or the largest leaves at the growth tip (the rito) and the surrounding support leaves. These ensure the plant continues to grow. Instead, leaves are taken from the sides (the ‘children’).
• Harvest from the East: Traditionally, plants are harvested from the east side first, facing the rising sun, which represents new life and vitality.
• Take only what is needed: There is a strict prohibition against stockpiling or wastage. One harvests only enough for the current preparation.
• Return to the Earth: After the medicine is prepared, the spent plant matter (mark) is returned to the earth, ideally near where it was harvested, to complete the cycle.

The ‘Big Three’: Kawakawa, Manuka, and Kumarahou

While the New Zealand bush is teeming with medicinal flora, three plants stand out as the pillars of Rongoā Māori healing plants due to their versatility, potency, and widespread availability. These are often the first species introduced to students of NZ herbalism.

Kawakawa (Piper excelsum)

Often referred to as the “pharmacy of the forest,” Kawakawa is perhaps the most ubiquitous healing plant in Aotearoa. Easily identified by its heart-shaped, bright green leaves, it is a relative of the Kava plant found elsewhere in the Pacific.

Medicinal Applications: Kawakawa contains myristicin and elemicin, which contribute to its mild analgesic and anti-inflammatory properties. Internally, it is revered as a digestive tonic, used to soothe stomach cramps, bloating, and indigestion. The leaves are often chewed to relieve toothache due to their numbing effect. Externally, Kawakawa is exceptional for skin conditions, including eczema, psoriasis, cuts, and insect bites. It is important to note that the leaves with holes in them—eaten by the looper caterpillar—are considered the most potent, as the plant produces higher concentrations of active compounds to defend itself against the insect.

Manuka (Leptospermum scoparium)

While Manuka is globally famous for the high methylglyoxal (MGO) content in its honey, the plant itself is a formidable rongoā. It is a scrub-type tree that acts as a nursery plant for regenerating forests.

Medicinal Applications: The bark and leaves of the Manuka tree are rich in tannins and antibacterial oils. A decoction of the bark was traditionally used as a sedative and to reduce fever. The leaves can be brewed into a tea to combat urinary tract infections and reduce inflammation. In vapor form, Manuka is excellent for respiratory congestion. The seed capsules, when chewed, act as a fast-acting remedy for diarrhea. In a professional wellness context, Manuka essential oil is increasingly used as a gentler, more complex alternative to Australian Tea Tree oil.

Kumarahou (Pomaderris kumeraho)

Known historically as “Gumdiggers Soap” because the flowers create a natural lather when rubbed with water, Kumarahou is the premier respiratory herb in the Rongoā pharmacopeia.

Medicinal Applications: Kumarahou is intensely bitter, a flavor profile often associated with liver support and blood purification in Western herbalism as well. Its primary traditional use, however, is for the lungs. It is an expectorant, helping to clear mucus from the bronchial tubes, making it invaluable for bronchitis, asthma, and winter colds. It is also used as a general tonic to “cleanse the blood” and support the kidneys. Because of its bitterness, it is often combined with Manuka honey to make it palatable for children.

Traditional Preparation Methods (Rongoā Rākau)

The efficacy of Rongoā Māori healing plants relies heavily on how they are prepared. The methods are designed to extract the specific constituents required for the ailment being treated. In the context of NZ Multi-Cultural Herbalism, these traditional methods often parallel Western herbal preparations but maintain distinct cultural nuances.

Wairākau (Infusions and Decoctions)

Wairākau refers to liquid medicine. For delicate plant parts like leaves and flowers (e.g., Kawakawa), an infusion is used where hot water is poured over the plant material and allowed to steep. This preserves volatile oils that might be destroyed by boiling. For tougher materials like bark, roots, or berries (e.g., Manuka bark), a decoction is used. This involves simmering the plant material in water for a sustained period to extract minerals and deeper tannins. Water used for wairākau should ideally be pure, sourced from a flowing stream or rainwater, honoring the connection to Papatūānuku (Earth Mother).

Pulu (Poultices)

For immediate first aid, pulu are essential. This involves crushing fresh leaves or roots to release their juices and applying the mass directly to the skin. A chewed Kawakawa leaf applied to a boil or insect bite is a classic example. The heat from the body, combined with the moisture of the plant, helps to draw out infection and soothe inflammation. In modern practice, this is sometimes adapted into a compress using a strong decoction and a clean cloth.

Pani (Balms and Oils)

Traditionally, animal fats (such as bird fat) or oils were used as a carrier for plant medicine. Today, pani are commonly made using olive oil, coconut oil, or almond oil infused with rongoā plants, then thickened with beeswax. A Kawakawa balm, for instance, is a staple in many New Zealand households. The process involves slow-infusing the leaves in oil (often using a double boiler to prevent burning) to transfer the lipid-soluble compounds, resulting in a potent healing salve for skin irritations, diaper rash, and eczema.

Integrating Rongoā with Modern Wellness

The landscape of wellness in New Zealand is shifting towards a more integrative model where Rongoā Māori healing plants sit alongside Western medicine and naturopathy. This resurgence is driven by a desire for sustainable, local healthcare solutions and a deeper cultural connection.

Clinical Application and Research

Scientific research is increasingly validating traditional knowledge. Studies on Kawakawa have isolated di-piperamide E, confirming its anti-inflammatory efficacy. This scientific backing allows integrative practitioners to prescribe Rongoā with confidence, bridging the gap between clinical evidence and traditional wisdom. Wellness clinics and spas are now incorporating Rongoā into their therapies, offering Manuka facials, Harakeke (flax) gel treatments, and Mamaku (black tree fern) hydration therapies.

Cultural Safety in Integration

For non-Māori practitioners utilizing these plants, cultural safety is paramount. This involves acknowledging the source of the knowledge and avoiding the appropriation of the culture. It means understanding that Rongoā is not just a commodity but a taonga (treasure). Professional herbalists in NZ are encouraged to engage with local iwi (tribes) and Rongoā practitioners to learn the specific tikanga of their region, as variations in practice and plant use exist across the country.

Safety, Identification, and Conservation Status

While natural, Rongoā Māori healing plants are potent and must be treated with respect. Misidentification or improper use can lead to adverse effects, and environmental pressures threaten the availability of some species.

Identification and Toxicity

Accurate identification is critical. Some native plants are highly toxic. For example, the Tutu (Coriaria arborea) is a poisonous plant that can be fatal if ingested. Its young shoots can look superficially similar to other edible shoots to the untrained eye. Furthermore, honey produced by bees feeding on Tutu (toxic honey) can be dangerous. Practitioners must be rigorously trained in botany to distinguish between similar-looking species. Additionally, dosage is key; even beneficial plants like Kumarahou contain saponins which, in excess, can irritate the stomach lining.

Conservation and Myrtle Rust

The conservation status of New Zealand’s flora is a pressing concern. Myrtle Rust, a fungal disease carried by the wind, poses a severe threat to the Myrtaceae family, which includes Manuka, Kanuka, and Rata. This disease attacks young growth, preventing the plants from regenerating. Harvesters play a crucial role in biosecurity by checking plants for the distinctive yellow powdery spores before touching them and ensuring they do not spread the disease on their clothing or equipment. Sustainable harvesting is no longer just a cultural preference; it is an ecological necessity to prevent the extinction of these taonga species.

In conclusion, Rongoā Māori healing plants offer a profound avenue for wellness that encompasses the physical and the spiritual. By adhering to tikanga, respecting the environment, and understanding the potent properties of plants like Kawakawa, Manuka, and Kumarahou, we can integrate this ancient wisdom into modern lives safely and sustainably.
