Botanical Description
The False Acacia, also known as black locust, is a tree that is native to North America. It is a member of the pea family (Fabaceae) and is closely related to the true acacias. The European acacia trees can grow up to 23 m (75 feet) tall and have a lifespan of up to 100 years.
The leaves of this tree are compound and have 7 to 19 leaflets, that are oval-shaped with a serrated edge. The flowers of false acacia trees are white or pale yellow and are borne in clusters, whilst the fruit of false acacia trees is a legume that contains several seeds.
These acacia trees are found in a variety of habitats, including forests, woodlands, and open areas. They were also commonly planted as ornamental trees and have escaped into the wild in many places – especially in Hungary. False acacia trees are a valuable source of nectar for bees and other pollinators and the wood is strong and durable and is used for a variety of purposes, including furniture making and construction.
False acacia trees are considered to be invasive species in some areas, but Hungary now considers them a ‘Hungaricum’ and protects the Acacia forests. They can outcompete native plants and can cause damage to infrastructure.

Harvesting
The flowers are the most commonly harvested part of the plant, and they are typically harvested in the spring when they are in bloom. The flowers should be harvested by cutting the entire flower cluster.
The seeds, pods, and leaves of the plant contain a toxin called robinin which can cause nausea, vomiting, diarrhoea, and abdominal pain if consumed in large amounts. In severe cases, robinin poisoning can lead to death.

Possible Side Effects
