It is said to be "helpful where there is fixed and unyielding mental perspectives, helping the person to make shifts and changes from a calm and centred point, relieved of agitation with space for new thoughts and ideas to emerge."

 

Traditionally used for several disorders “Reactive, agitated and masked depressions, melancholy, neurasthenia, neuropathy, organic neurosis, vegetative-dystonic disturbances, imbalances, constitutional lability of the nervous system”, as well as a sleep-inducer and sedative tea.

 

A too high dose has been reported to make people feel too sedated, too heavy and cumbersome. Again, the best dose is the amount that the person can palpably feel relaxing them and making them feel more comfortable." [1]

 

Both aerial parts and roots contain alkaloids, the latter being much richer (1.6-2.7%). Six flavonol 3-O-glycosides were isolated from the aerial parts [2]
 

Relative safety is evidenced by traditional use of the plant, which can be found in the European market for more than 30 years without any safety concern.

 

- Affinity for the benzodiazepine receptors and alkaloids increase the binding of GABA to GABA receptors
- Binding to 5-HT1A and 5-HT7 receptors

 

Typical pharmacy preparations (i.e., 300 mg of dry plant material per capsule, twice daily) theoretically contain insufficient quantities of these alkaloids required to induce desired biological effects. It is evident from HPLC analysis that protopine and a-allocryptopine levels in the aerial parts of this herb are too low to modulate significantly the chloride-ion flow across the GABAA receptors at traditional doses. In order to achieve important medicinal effects (regarding relatively low alkaloid levels determined in aerial parts of this plant), one would need to increase the dried plant dosage above 1 g [3]

 

The aqueous extract of the plant at 25mg/kg in mice exerted an anxiolytic action, as proved by changes in behavioural parameters; at higher levels, the effect became more sedative. The anxiolytic and sedative effects of E. californica are caused by affinity for GABA receptors, as evidenced by suppression of anxiolytic and sedative effects following pre-treatment with flumazenil.

 

While it has potential of causing interactions with drugs that are metabolized by cytochrome P450s, the tea seems to be safer [4].
