Although it is sometimes referred to as a "false acacia" due to its strong resemblance to true botanical acacia flowers, the blossom of the black locust tree (or the "false acacia blossom") has many genuine benefits. Recognised since ancient times, it is still widely used today; we explain why and how.

What are acacia blossoms?

The herbal bloom commonly referred to as "acacia flowers" come from the black locust tree (robinia pseudoacacia), a tree of the Fabaceae family native to North America. Growing to a height of up to 30 metres, the black locust tree produces large clusters of small white flowers in spring, which may sometimes be yellow or pink depending on the species. These flowers are very fragrant and fill the air with a sweet scent reminiscent of the orange blossom. These blossoms are very delicate and remain fresh for only a few hours after being picked.

As an interesting fact, the black locust or pseudo acacia owes its name to Jean Robin, botanist to Kings Henry IV and Louis XIII. He is said to have been the first to bring its seeds back to France in 1601 and to have named it thus because of its resemblance to tree species of the genus Acacia. Although the term has since become widely used in everyday language, it is not entirely correct from a botanical point of view to refer to these as "acacia flowers" because they do not come from a true acacia tree. The "true" acacia, on the other hand, belongs to the Mimosaceae family. Often native to Africa or Australia, it bears small, pompom-like yellow flowers that are generally not edible.

What are its benefits?

  • Anti-inflammatory: Acacia blossom helps to reduce inflammatory reactions in the body. It is effective at soothing irritation (of the skin or throat) and digestive discomfort (heartburn, bloating, mild constipation).

  • Antiseptic: it helps to disinfect superficial skin wounds. Acacia honey, derived from false acacia flowers, soothes the throat.

  • Expectorant: it helps to thin and expel bronchial secretions. It is particularly useful for relieving coughs and mild respiratory conditions.

  • Tonic: it has a general tonic effect on the body. It promotes good vitality, improves digestion and helps manage energy levels more effectively on a day-to-day basis.

  • Soothing : acacia flower infusions are renowned for calming the nervous system, reducing anxiety and improving sleep quality. They also soothe stomach aches, heartburn and mild throat irritation.

  • Antioxidant: it contains flavonoids, natural compounds that neutralise the free radicals responsible for oxidative stress and cellular ageing.

Why use it?

As a herbal tea

To aid digestion, soothe spasms and promote relaxation. Acacia flower infusions are ideal after a meal or in the evening to benefit from their digestive and soothing properties. Steep 1 to 2 tablespoons of dried acacia blossoms in 250 ml of simmering water for 10 minutes, then strain.

In the bath

To relieve stress, create a soothing atmosphere, and soften and revitalise the skin, add a handful of dried flowers to your bath water and leave to infuse for a few minutes. A bath infused with acacia flowers creates a restful atmosphere, perfect for unwinding after a stressful day.

As a compress or poultice

To soothe irritation, promote the healing of minor wounds, cuts or burns, stimulate tissue regeneration, help prevent infections and protect the skin from drying out.

  • To make a compress: prepare a concentrated infusion of acacia flowers, then soak a sterile compress or a clean cloth in it. After wringing out the excess water, apply the compress to the affected area for 10 to 20 minutes.

  • To make a poultice: finely chop fresh or dried acacia flowers, then crush or blend them to form a purée. Add a little lukewarm water and spread this thick paste onto a clean cloth. Place the poultice on the affected area, perhaps after applying a little vegetable oil to the skin to prevent the paste from sticking. Leave it on for 20 to 30 minutes, securing it with a soft bandage. Remove, then rinse with water.

In homemade cosmetics

To soften and moisturise the skin, soothe irritation and inflammation, help protect the skin against ageing and free radicals, and to tone the skin. To do this, use your homemade acacia flower infusion as a facial toner, or mix it with white or pink clay to create a soothing face mask. Leave the mask on for 10 to 15 minutes before rinsing off with lukewarm water.

In cooking

For a sweet, floral note, a subtle fragrance that enhances the flavour of a sweet dish without overpowering the other flavours, and a decorative, refined touch. Acacia flowers are highly prized in cooking, particularly in fritters, jams, syrups, salads and desserts. Their honeyed flavour and slightly crunchy texture are sought after in sweet dishes.

In honey: To soothe sore throats, soften the skin, calm irritation and speed up the healing of minor wounds. Acacia blossom honey can be used both in food and in homemade cosmetics (face masks, moisturisers, poultices for the skin or even the hair).

Acacia flower and acacia gum: what’s the difference?

Although they have almost the same name, acacia flower and acacia gum are two very different products with different compositions and uses. Firstly, they come from different trees. What is commonly known as ‘acacia flower’ is in fact the flower of the black locust tree, from the Fabaceae family, which does not belong to the genus Acacia in the strictly botanical sense. The black locust tree produces edible white flowers and does not produce gum.

Acacia gum (also known as gum arabic), on the other hand, is harvested from trees of the genus Acacia, mainly Acacia senegal and Acacia seyal, which are native to Africa. Rich in polysaccharides and soluble fibre, it is recognised for its benefits for digestion and its technical uses as a thickener, emulsifier, stabiliser and texturiser.

Contraindications and precautions

It is important to consume only the (false) acacia flowers, as other parts of the black locust tree, such as the leaves and seeds, can be toxic. Make sure you pick these flowers away from sources of pollution and consume them soon after harvesting to enjoy their full freshness. They must be fully open, rinsed and stripped of their stems, sepals and pistils before use. If you have any allergies, are pregnant or are breastfeeding, seek advice from a healthcare professional.

Expert advice

Be sure to identify the plant correctly. Laburnum and black locust look very similar! Laburnum has leaves very similar to those of black locust and the same clustered inflorescences. However, its flowers are yellow and poisonous.
