Kowhai Tree: An Introduction

Kowhai trees (Kōwhai) are iconic native plants in New Zealand. They are more often found on river banks or alongside forest margins but their aesthetic appeal has also made them popular in garden landscaping across the country.

Easy to recognize with their brilliant yellow flowers that usually bloom during spring, they range from small shrubs to towering trees up to 25 meters tall.

Name ‘kowhai’ is taken from Maori term for ‘yellow’ which describes vivid hue of its distinctive flowers – a delightful sight that serves as an indicator of Springtime’s arrival in New Zealand.

Besides their striking looks, these deciduous trees also have an important role within Maori culture where they symbolize strength & bravery.

Interestingly, every aspect of Kowhai tree – right from bark & leaves down to its seeds – was utilized by pre-European Māori for medicinal purposes despite its toxic properties suspected by scientists today. The gum obtained from it was used for relieving cold symptoms while bruised leaves were applied to wounds or ulcers.

Despite being respected & admired for centuries now, a question looms over how safe it really is due to certain natural components present within this plant species; Is kowhai poisonous?

4 Natural Components of Kowhai Trees

Kowhai trees contain several natural components that contribute both positively & negatively to human health.

Component	Type	Effect	References
Tannins	Beneficial	Helps in water infusion, may have astringent effects	Traditional medicinal use by Māori
Phenolic Compounds	Beneficial	May have antioxidant properties	Medicinal use by Māori
Cytisine	Toxic Alkaloid	Can cause nausea, vomiting, muscle weakness, convulsions & even death if ingested	‘Although kōwhai is traditionally known to Māori as a medicinal plant used externally… internal use could result in serious health effects’ – Landcare Research
Alkaloids (general)	Toxic	Found in seeds, pods & young leaves Causes bitterness & toxicity to deter herbivores	Scientific studies on alkaloids in leguminous plants

Cytisine

Cytisine is a quinolizidine alkaloid naturally produced as a defense mechanism against herbivores by various leguminous plants including kōwhai (Sophora spp.).

It’s closely related chemically to nicotine thus exhibiting similar pharmacological effects when ingested.

Alkaloids

As mentioned earlier, they deter herbivores from feeding on kowhai trees due to their bitter taste & poisonous effect.

Whilst this proves advantageous for kowhai’s survival in wild, it raises concerns among human populations interacting directly with these trees – particularly gardeners who might be unaware of possible risks involved.

Part of the Tree	Potential Toxicity	Safe Usage
Flowers	Low toxicity when boiled	Recorded without any adverse effects, granted they have been used cautiously after proper preparation Boil flowers before consumption to reduce toxins
Seeds	Highly toxic (contains cytisine)	Avoid ingestion, especially by children or pets
Leaves	Contains alkaloids, toxic in large amounts	Avoid consumption of raw leaves
Bark & Gum	Traditionally used for medicinal purposes	Use externally for treating colds or wounds (with care)

Effects and Dangers of Kowhai Tree Ingestion

As alarming as it sounds, clinging to toxicity factor alone would not give us a complete understanding of real-life incidents – especially since cases involving kowhai poisoning are reported so infrequently.

Ingested Component	Symptoms	At Risk	Sources
Cytisine (seeds)	Nausea Vomiting Muscle weakness Convulsions Death in extreme cases	Humans Pets (especially dogs and cats) Livestock	Landcare Research
