ESCHSCHOLTZIA (Eschscholtzia californica)
Where did he come from?
The “California yellow poppy”, a major plant of the nerve sphere, is essentially known for its mild sedative and antispasmodic virtues. Eschscholtzia californica is also called California poppy because it is native to the west coast of the United States.
The Indians mainly ate his leaves as vegetables. They would boil them or grill them on hot stones. He entered Europe in the 19th century as an ornamental plant by a Russian botanist, J.F.G. Eschscholtz, hence its name: Eschscholtzia.
Native Americans also used latex as an analgesic in toothache and colic.
How can we describe it botanically?
Eschscholtzia is an annual, perennial plant. It forms a tuft 30 cm high by about 45 cm wide. Its topped leaves are finely cut and bluish in colour. They can be 15 to 20 cm long. Its fruits form long arched pods. The corolla of its flowers with two deciduous sepals closes each evening by straightening its four free petals, yellow to orange yellow. Eschscholtzia grows on all soils, even limestone, but only blooms from May to September.
What is it made of?
Eschscholtzia consists mainly of alkaloids, pavines, protopines, benzophernanthridines, aporphins, protoberberins, benzytererahydroquines and flavonoids.
What are its main pharmacological properties?
Eschscholtzia-based preparations would reduce the duration of sleep and improve its quality. The anxiolytic action is due to certain alkaloids, such as protopine.
Eschscholtzia has spasmolytic and sedative properties, in an association Eschscholtzia and Corydalis cava in respective proportions 80-20%, with an activity on endorphins. Anxiolytic activity is demonstrated in particular by a study of 264 patients with generalized anxiety (DSM-III-R) of low to moderate intensity, it is a mild sleeping pill, a painkiller and an analgesic per action on encephalins, recommended in pediatrics. Hypnotic and sleep-inducing, it consequently decreases the time it takes to fall asleep and prolongs sleep duration by inhibiting the enzymatic degradation of catecholamines.Eschscholtzia, however, has an effect on serotonin by some alkaloids that bind to 5-HT serotonin receptors (protopine, aporphine).
The benzophenanthridines it contains, however, have an affinity for V1 receptors in rat liver vasopressin and could provide non-peptide models for the design of synthetic vasopressin compounds.The effects are demonstrated by Dr. J.Fleurentin: low-dose anxiolytic – high-dose sedative – gaga-A modulation of sleep – analgesic effect.
Thus the traditional therapeutic indications of Eschscholzia are largely confirmed by pharmacological experiments in animals, however the active ingredients are not currently identified with certainty according to the scientific literature (Dr Fleurentin).Some isoquinoleic alkaloids (hunnemanine, norsanguinarine) are antifungal (Alternaria sp., Curvularia sp, Helminthosporium sp, Fusarium sp.).
What are the indications of the Eschscholzia?
- Child neuropathy
- Nocturnal enurestia
- Difficulties of falling asleep
- Multiple nocturnal awakenings
- Non-restorative sleep
- Nightmares in children
What are the job precautions?
- Under-indicated in pregnant or lactating women, as well as in children under 6 years of age
- Contrainditated in case of glaucoma
Are there risks of drug interactions?
Like all substances containing active ingredients, the risk of drug interactions is therefore to be taken into account.
Eschscholtzia is no exception to this rule, but here is a list of drug interactions to consider:
- Avoid in combination with anti-depressants and anti-hypertensives
How to take it and at what dosage?
