How to Harvest Black Locust Flowers

Black locust flowers are in bloom starting in early May and continue blooming until June in mountainous areas. Harvest only the flowers of the young branches, where they are easier to reach. The black locust flowers are harvested, along with the bunches on which they are arranged, but without leaves, which are harvested and dried separately for other uses.

Only white black locust flowers (Robinia pseudoacacia L) are used in natural remedies, the colored black locust flowers may be poisonous and we do not recommend using them without being properly informed.

Health Benefits of Black Locust Flowers

Black locust flowers (Robinia pseudoacacia L) have anti-acid and gastric calming effects. The reason is that they contain small amounts of robinin, and acaciin – a glycoside, flavonoids, essential oils, tannins, caffeic and chlorogenic acids, and carbohydrates.

Due to their mild alkaline reaction, black locust flowers are recommended as a neutralizer of gastric acidity, as they buffer excess stomach acidity but also as a medicinal tea to relieve cough. Another one of the less-known health benefits of black locust flowers is their soothing effects on the nervous system, making them a great remedy for anger, or impulsiveness. They reduce nervous excitability, being very useful in headaches and nausea that worsen with sound and auditory stimuli. The most important health benefits of black locust flowers are:

  • gastritis
  • high stomach acid
  • cough and bronchitis
  • anticancer
  • migraines and headaches
  • stress and irritability
  • insomnia
  • menstrual cramps
  • yeast infection
  • leucorrhea
  • oral thrush
  • oral health

“Robinia pseudacacia is prescribed for hyperacidity and related gastrointestinal disorders, such as acid dyspepsia, heartburn, gastritis, acid, bitter acid reflux, as well as stomach bleeding and gastric caused headache.”

Gerhard Madaus, Textbook of Biological Healing Methods, 1938

3 Ways to Use Black Locust Flowers as Medicine

1. How to Make Black Locust Flowers Powder

Grinde the dried black locust flowers as finely as possible with an electric coffee grinder. The powder is stored in sealed glass jars, in a dark and cold place, for a maximum of 2 weeks (because the volatile substances evaporate quickly). Usually, it is administered one leveled teaspoon 4 times a day, on an empty stomach.

2. How to Make Black Locust Flowers Infusion

Put a teaspoon of dried black locust flowers in a cup of boiling water, then cover and steep for 10-15 minutes. Strain and drink the tea as hot as possible. Optionally, sweeten with locust honey. The therapeutic effects of the flowers are greatly diminished when making the hot infusion, following the scalding of the plant (some active principles are destroyed). But due to the thermal effect, the antispasmodic, bronchodilator, or sweating properties are amplified. However, in most cases, the combined infusion is preferred, which has extensive therapeutic effects.

3. Black Locust Flowers Combined Infusion Recipe

To make the combined infusion put 3-4 tablespoons of the chopped dried flowers to soak in half a liter of water for 12 hours, then strain. The resulting cold macerate is set aside, and the plant left after filtration is boiled in another half liter of water for five minutes. Leave to cool off and strain. Mix the two together and you have approximately one liter of combined black locust flowers infusion. You can have 1-2 cups per day, or use it externally, in the form of compresses and baths.

Are Black Locust Flowers Edible?

Yes, they are and can be used raw in salads, but also pan-fried in a flour batter to make a delicious side dish. You can also use them to prepare a simple locust flower cordial, similar to the elderflower cordial recipe. So delicious! Only white black locust flowers (Robinia pseudoacacia L) are edible, the colored black locust flowers may be poisonous and we do not recommend using them without being properly informed.

10 Black Locust Flowers Remedies & How to Use

1. Gastritis

Ongoing studies indicate that black locust flowers also act on the central nervous system, reducing the body’s response to mental stress, which would better explain the beneficial effects of this plant in gastritis that occurs in people who are mentally overworked or who are emotionally unbalanced.

For gastritis, you can use dried black locust powder (1 tsp 4-6 times/day on empty stomach for at least a month; pause and resume if needed) or prepare a cold macerate with black locust flowers by steeping 3 tbsp of dried locust flowers in 1 l of cold water for 12 h. Strain and have a cup before every meal. Or, you can also make the hot infusion and have 2 cups a day, before meals.

2. Stomach Acid

If you suffer from high stomach acidity, we recommend black locust flowers tea as prepared above. Concomitantly, you can have a cold macerate calamus root and have 6 tablespoons of this macerate a day. You can continue drinking both these teas until your stomach acidity is back to normal. If you also suffer from acid reflux, you can have one tablespoon of equal parts of black locust flower powder and raspberry leaves powder, 10-15 minutes after each meal. Both these plants have anti-acid and antispasmodic effects, helping to control and reduce acid reflux.

3. Migraines

In this case, prepare 1 liter of combined infusion (recipe above) and sweeten with locust honey. If you suffer from headaches and related phenomena due to mental fatigue, you can follow a 4-week course of treatment, in which you use equal parts of black locust and linden flowers to prepare the combined infusion. During the cure, it is ideal to reserve more time for sleep, as this combination of flowers helps the nervous system to recover through rest and relaxation.

5. Yeast Infection and Oral Thrush

Prepare a concentrated combined infusion (3 tablespoons per cup of water) with black locust flowers and leaves. Use this preparation to do vaginal irrigations every morning, by holding the infusion in the vagina for at least 7 minutes, before elimination. It is an excellent treatment for this condition, because, in addition to having strong antifungal effects, black locust infusion does not destroy the good bacterial flora, and can be used daily for long periods of time.

This same remedy can also be used internally for oral thrush. In this case, prepare the same concentration combined infusion and drink throughout the day. It has antifungal effects and helps to regulate the body’s acidity over time (an important element in keeping yeast infection under control).

6. Vaginal Discharge

The most effective natural treatment for vaginal discharge (leukorrhea) is black locust flower infusion. Prepare the infusion following the abovementioned recipe. Have three cups a day for ten days straight. You can also perform vaginal douches with black locust flowers infusion. Healing is 100% guaranteed if you also reduce or cut out sugar, sweets, and artificial sweeteners with fresh, ripe fruit.

May, the month in which flowers and human hopes spring up. It is the guardian tree of change, of things that follow stagnation.
