Lippia abyssinica, or koseret (Amharic: ኮሰረት, romanized: koserēt), is a species of flowering plant in the verbena family, Verbenaceae.

In French it is called verveine d’Afrique (literally 'African verbena'),[3][14] Brégué Balenté, or Mousso et mâle.

[16] Some describe its flavor as being similar to basil,[17] but it is not closely related to that herb (they are merely in the same order, Lamiales).

Koseret along with the other herbs and spices preserve the butter and oil, preventing spoilage for up to 15 years.

[2][3][13] The plant has also been used as traditional medicine for cough,[12][16][3] fever,[7][16][3] constipation,[12] and cutaneous conditions[12][6] such as burns.
