Bay leaf: benefits, dosage and precautions

bay leaf infusion benefits

Bay leaf is one of the most common aromatic herbs in Moroccan kitchens and traditional remedies, where its leaves flavour tagines as much as they soothe digestion. Behind this familiar foliage lies a medicinal plant whose virtues have been recognised since antiquity. In this article, we review the benefits of bay leaf, its composition, how to use it, the right dosage and the precautions to follow.

What is bay leaf?

Bay laurel (Laurus nobilis), also called sweet bay or “rand” (رند) in Morocco, is an evergreen shrub of the Lauraceae family. Native to the Mediterranean basin, it grows wild in several regions of the country and is recognisable by its dark green, leathery, glossy leaves with an intense fragrance.

Not to be confused with oleander or cherry laurel, which are toxic, bay laurel is the only edible and medicinal laurel. Its dried leaves keep for a long time and are used in cooking as well as in herbal teas and essential oil.

Composition and active compounds of bay leaf

Bay leaves owe their properties to a remarkable wealth of aromatic compounds. These include:

  • an essential oil dominated by 1,8-cineole (eucalyptol), which can account for around 40% of its composition;
  • other terpenes such as p-cymene, alpha-terpinyl acetate, myrcene and beta-pinene;
  • linalool and eugenol, with soothing and purifying properties;
  • tannins, a bitter principle, mucilage, as well as resinous and pectic substances in the leaf.

This combination of monoterpenes, oxides and esters explains the digestive, antispasmodic and anti-inflammatory action traditionally attributed to the plant. The exact composition varies depending on the growing area, the season and the drying method.

The health benefits of bay leaf

Used for centuries in folk medicine, bay leaf is best known for its action on the digestive system, but its uses do not end there.

An ally for digestion

This is its best-documented virtue. Taken after a meal, a bay leaf infusion helps reduce bloating, intestinal gas and feelings of heaviness. Its stomachic and antispasmodic properties promote more comfortable digestion.

Anti-inflammatory and antispasmodic action

The terpene compounds in the leaf give it anti-inflammatory and antispasmodic effects, traditionally used to relieve digestive tension and some mild pain.

Support against fatigue

Bay laurel is traditionally considered a tonic: it is said to help restore energy in cases of physical or mental fatigue, particularly as an essential oil diluted for external application.

Purifying properties for the skin and scalp

Thanks to its aromatic molecules, bay laurel essential oil is recognised for its purifying properties. It is used to cleanse the skin and scalp and to support the body’s natural defences.

How to use bay leaf and dosage

Bay leaf is most often taken as an infusion or decoction. Here are the dosage guidelines usually recommended:

  • Infusion: about 10 g of dried leaves per litre of water, or more simply 2 to 3 leaves per 250 ml cup of simmering water, left to steep for 10 minutes.
  • Decoction: about 30 g of leaves per litre of water, brought to the boil for a few minutes for a more concentrated effect.
  • Essential oil: for external use only and always diluted in a vegetable oil; it is not recommended orally without professional advice.

For digestion, one cup after the main meal is generally enough. In cooking, one or two leaves added to a slow-cooked dish provide both aroma and a mild digestive effect.

Precautions and contraindications

Taken in moderation, a light bay leaf infusion poses no problem for a healthy adult. A few precautions nonetheless apply:

  • avoid prolonged daily use at high doses without medical advice;
  • caution during pregnancy or breastfeeding, when the essential oil in particular is not recommended;
  • caution for people taking anticoagulants or undergoing medical treatment;
  • never confuse edible bay laurel with oleander or cherry laurel, which are toxic;
  • if in doubt or if you are prone to allergies, seek advice from a healthcare professional.

Bay leaf FAQ

Can you drink bay leaf tea every day?

A light cup after a meal can be taken occasionally without any problem by a healthy adult. For daily and prolonged use, it is best to seek the advice of a healthcare professional.

Does bay leaf help you lose weight?

Bay leaf is not a fat burner. It can simply support more comfortable digestion and reduce bloating, which gives a feeling of lightness, but it does not replace a balanced diet or physical activity.

What is the difference between bay leaf and its essential oil?

The leaf is used in infusions or in cooking, with a gentle action. The essential oil is a very powerful concentrate, reserved for diluted external use, to be handled with care and preferably on the advice of a specialist.
