Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Analgesic  Antirheumatic  Nervine  Poultice  Salve  Stimulant  Stomachic

California laurel was employed medicinally by some native North American Indian tribes who used it particularly as an analgesic to treat a variety of complaints[257]. It is still occasionally used in modern herbalism, being valued for its beneficial effect upon the digestive system. The leaves are analgesic, antirheumatic, nervine and stomachic[92, 94, 95, 238, 257]. Although the aroma of the leaves is known to cause headaches, they have also been used as an infusion and a poultice to treat this affliction[92, 94, 95, 238, 257]. The leaves are also used internally to treat neuralgia, intestinal cramps and gastro-enteritis[238]. An infusion has been used by women to ease the pains of afterbirth[257]. Externally, an infusion has been used as a bath in the treatment of rheumatism[257]. A decoction of the leaves has been used as a wash on sores and to remove vermin from the head[257]. They are harvested as required and can be used fresh or dried[238]. A poultice of the ground seeds has been used to treat sores[257]. The seeds have been eaten as a stimulant[257].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Other Uses

Dye  Essential  Incense  Repellent  Wood

The leaves are used as an insect repellent, they are especially effective against fleas[62, 92, 94, 95, 169]. They have disinfectant properties and contain small quantities of camphor[95, 169]. The leaves are burnt as a fumigant to get rid of fleas[257]. The leaves have been hung in bunches to freshen the air[257]. The aroma of the leaves gives some people headaches[K]. An essential oil is obtained from the leaves by steam distillation[11, 46, 61, 82]. Beige and green dyes are obtained from the fruits (used without the seeds). Very aromatic, the dye retains its fragrance for many years[168]. Wood - hard, close grained, heavy, strong, takes a high polish. A beautifully textured wood, it is used for high quality cabinet making, panelling etc[61, 82, 94, 229].

Cultivation details

Landscape Uses:Hedge, Aggressive surface roots possible, Screen, Specimen, Street tree, Woodland garden. Requires a well-drained moisture retentive lime-free soil in a sunny position[200]. Prefers an abundant supply of moisture in the growing season[82]. Older plants are hardy to about -15°c when growing in a position that is sheltered from cold drying winds, but young plants require some frost protection[200]. Even mature plants can be damaged in severe winters[1]. The leaves are harvested commercially in California and sold as a bay-leaf substitute[183]. The leaves emit a powerful camphor-like scent when bruised[245]. So strong is the aroma that it can cause headaches and dizziness[245]. A very large and beautiful tree fruited regularly at Kew, producing viable seed, until it was blown down in the severe storms of October 1987[K]. Special Features:Attracts birds, North American native, Fragrant foliage, Inconspicuous flowers or blooms.

Propagation

Seed - it has a limited viability and is best sown as soon as it is ripe in the autumn in a greenhouse[200]. Stored seed should be sown as early in the year as possible in the greenhouse. In the wild the seed germinates as soon as it falls to the ground in the autumn[82]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in a shaded frame. Pot up in spring. Good percentage[78, 200]. Layering.

This is one of my favorite plants with so many uses in my area (its native range) that I'm stunned this plant is not more widely known. I'm glad to see it given a 4 out of 5 for usefulness in a site based out of the UK. In my area, it is one of the most common wild trees, and I enjoy sitting under their shade on hot dry days. The nuts are such a unique and amazing food, that I can only think bad cultural and political thoughts when I think about why it is not a traded commodity (like chocolate or coffee.) There is a strong bias against foods that are native to California, demonstrating a pathological denial of the terrible genocide and ecocide that happened here. Another great use of this tree is for climbing, something that is rarely considered in landscaping.

A tasty beverage may be made by roasting the seeds and then grinding them in a coffee grinder. Take the resulting powder and put it in a frnech press, fill with hot water and wait five to ten minutes. I find the beverage is even better with some milk and sugar added.
