Queen Anne’s lace or wild carrot

Queen Anne’s lace or QAL, Daucus carota (syn. D. abyssinicus, D. aegyptiacus, D. azoricus, D. bocconei, D. gingidium, D. glaberrimus, D. gummifer, D. halophilus, D. hispanicus, D. hispidus, D. maritimus, D. mauritanicus, D. maximus, D. micranthus, D. parviflorus, D. polygamus and D. rupestris!), is also known as eastern carrot, hu luo bo, Mediterranean carrot, Queen’s lace, salosi, sea carrot and wild carrot. Although it is extremely pretty in its second year when it flowers, it should never be collected from the wild, because like all umbelliferous plants (family Apiaceae) it is easy to mistake for hemlock, which is very poisonous.

The name Queen Anne’s lace is also used for Bishop’s weed, which is in the same family but not closely related.

QAL is a hardy biennial but is almost always treated as an annual. It can reach a height of 1m (3′) and a spread of 30cm (1′). It requires full sun, and should be sown in rich soil fertilized for the previous crop. Sow direct very thinly in v-shaped trenches any time from early Spring to mid-Fall. An alternative method is station sowing (sowing 2 or 3 seeds at the desired final spacing). Final spacing is 10cm (4″) x 15cm (6″). Keep well weeded and thin to a single plant per station (or thin to final spacing). Foliar feed twice a week with half-strength seaweed fertilizer for the best results.

Avoid growing at the same time as other Apiaceae grown for seed production, eg. fennel, dill, coriander. If you don’t want seed, the flowers should be removed. I guess you could use them for flower arrangements, but I don’t know how long they keep in water.

Cut one or two leaves per plant as required for medicinal use. Pull up whole plants for dye 4-5 months after sowing, or in July for remedies. Can be dried for later use.

NB: Queen Anne’s lace may cause allergic reactions and sap may cause photo-sensitivity and/or dermatitis in some people. Handling carrot leaves, especially when wet, can cause irritation or even blisters. According to Plants for a Future, “sensitized photosensitive persons may get an exact reproduction of the leaf on the skin by placing [it] on the skin for awhile, followed by exposure to sunshine.”

The roots can be cooked, but don’t come close to cultivated carrots either for tenderness or size. Deep fried flowerheads apparently produce a gourmet’s delight. The seed can be used as a flavoring for soups and stews. Dried powdered roots have been used as a coffee substitute.

NB: Queen Anne’s lace is not a suitable remedy during pregnancy or for anyone trying for a baby.

Make a standard infusion using 30 g (1 ounce) dried whole plant or leaves/3 handfuls of fresh whole plant or leaves/1 ounce of seeds (not from a packet, as these are usually treated with fungicide) to 500ml (2 US cups, 16 fl oz) water. The dosage is up to 250ml (1 US cup, 8 fl oz).

Queen Anne’s lace is a diuretic and cleansing medicine which soothes the digestive tract and stimulates the uterus. It supports the liver and stimulates the genito-urinary system.

An infusion of the whole plant is used as a diuretic, to clear obstructions and treat digestive disorders, edema (oedema), eye complaints, flatulence (“gas” or “wind“), kidney and bladder disorders and to promote milk flow in nursing mothers.

An infusion of the leaves has been used to help prevent kidney stone formation, to reduce existing stones, to stimulate the pituitary gland (and increase sex hormone levels) and for cystitis.

Grated raw root (also grated cultivated carrot) is used to expel threadworms and to induce menstruation and uterine contractions.

A root infusion is diuretic and can be used to treat kidney stones.

The seeds are diuretic and can be used to treat flatulence, promote menstruation and expel parasites. An infusion of seeds can be used to treat edema, indigestion and menstrual problems.

Carrot seed blocks progesterone synthesis. Carrot seed tincture and carrot flower tincture (3 doses consisting of 15 drops of each every 8 hours) have been tested as a contraceptive. Although only around 95% effective, this may well be helpful in the absence of any other method, for example for preppers. There was no reduction in fertility after the trial was completed.

As with all plants grown for medicinal use, it’s important that organic growing methods re used, to avoid the active constituents from being destroyed or adulterated by foreign chemicals. To find out more about organic gardening, visit the Gardenzone.


The essential oil is extracted from the seed and is usually labeled Carrot or Wild Carrot. NB: Carrot seed essential oil is not suitable for use during pregnancy. A single drop taken by mouth once a day is sometimes prescribed to aid liver regeneration. Apart from this and similar specific recommendations no essential oil product should be used internally.

Carrot seed oil is mainly used for skin rejuvenation and for dry and mature skin. It is also said to relieve fatigue. It is used commercially in anti-wrinkle creams, in perfumery and as flavoring.

As with all essential oils, carrot seed essential oil should never be taken internally, even though you may see this recommended elsewhere. Essential oils are highly concentrated and can cause permanent damage if used in this way, even if you think you have diluted them. Be safe and use them as intended, in massage blends and diffusers, and keep them out of the reach of children at all times.
