Description: Primula veris is a well-known wildflower, native to meadows and pastures throughout England, Europe and temperate Asia. A hairy perennial, it has loose rosettes of oblanceolate to obovate, wrinkled leaves, 50-250mm long. The lobes of the calyx are acute at the apex. The bright yellow flowers are funnel-shaped, 8-28mm across, with orange spots at the base of each lobe, all drooping to one side in a cluster of ten to thirty on a long naked stalk. The ripe capsule is shorter than the calyx, and contains dry seeds. The plant favours open woodland, scrub and grassland on lime-rich soils.
Parts used: flowers; occasionally the root
Collection: The flowers should be collected, without the green calyx, between March and May. The roots should be unearthed before flowering or in the autumn. Primula veris is becoming increasingly rare, so should not be collected in the wild.
Constituents: up to 10% saponin glycosides (particularly in the root, and including primulaveroside and primoveroside which contain salicylates), flavonoids (mainly in the flowers, including quercetin, luteolin, kaempferol and apigenin and their glycosides), phenolic glycosides, tannins, and about 0.1% volatile oil
Actions: sedative, spasmolytic, expectorant, hypnotic, mild diuretic, mild aperient
Indications: insomnia, nervous excitability, hysteria. Specifically indicated in anxiety states associated with restlessness and irritability.
Therapeutics and Pharmacology: Primula is a relaxing, sedative remedy, indicated in states of tension and nervous excitability. The flowers, which contain most of the essential oil known as ‘primula camphor’, are indicated in insomnia and nervous tension. The main active constituents are the flavonoids which exhibit anti-inflammatory and antispasmodic activity. They inhibit the release of histamine and act as free radical scavengers. The flowers also have a reputation for treating measles, and an ointment made from them brings relief to sunburn.
The high saponin content in the root probably accounts for its reputation in the treatment of pertussis and bronchitis, while the salicylates explain its use on the Continent in the treatment of arthritic conditions; the root was known as Radix arthritica in the past. The root is also thought to be mildly diuretic and to slow blood clotting.
Caution: The stamens may cause contact dermatitis.
Preparation and Dosage: (thrice daily)
Regulatory Status: GSL Schedule 1

Additional Comments: According to legend, cowslips first appeared from the ground where St. Peter dropped his keys, accounting for some of the common names of this plant. There used to be a widespread belief that cowslips would produce red flowers if they were planted upside down.
