FAMILY: Lamiaceae (Labiatae)
SYNONYMS: L. spica, aspic, broad-leaved lavender, lesser lavender, spike.
GENERAL DESCRIPTION: An aromatic evergreen sub-shrub up to 1 metre high with lance-shaped leaves, broader and rougher than true lavender. The flower is more compressed and of a dull grey-blue colour.
DISTRIBUTION: Native to the mountainous regions of France and Spain; also found in North Africa, Italy, Yugoslavia and the eastern Mediterranean countries. It is cultivated internationally; the oil is mainly produced in France and Spain.
OTHER SPECIES: There are many different chemotypes of lavender in general, and this also applies to spike lavender. The French spike oil is reputed to be a more delicate, aromatic scent than the Spanish variety. For other varieties, see entries on lavandin, true lavender and the Botanical Classification section.
HERBAL/FOLK TRADITION: Culpeper recommends spike lavender for a variety of ailments including ‘pains of the head and brain which proceed from cold, apoplexy, falling sickness, the dropsy, or sluggish malady, cramps, convulsions, palsies, and often faintings’. He also warns that ‘the oil of spike is of a fierce and piercing quality, and ought to be carefully used, a very few drops being sufficient for inward or outward maladies’.. The preparation ‘oleum spicae’ was made by mixing ¼ spike oil with ¾ turpentine, and used for paralysed limbs, old sprains and stiff joints (it was also said to encourage hair growth).
Spike lavender is current in the British Herbal Pharmacopoeia, indicated for flatulent dyspepsia, colic, depressive headaches, and the oil (topically) for rheumatic pain.
