Rating (out of 5): 2

California poppy (Eschscholzia californica) has a long history of use in traditional herbal medicine, particularly among Native American groups in California and herbalists in North America and Europe. It has been used to promote relaxation, ease mild pain, and alleviate states of nervousness or tension. Traditionally, the aerial parts of the plant were prepared as teas, tinctures, or poultices to address restlessness, agitation, and sleep disturbances—symptoms often associated with tension and stress. Early European settlers adopted these uses, and the herb remains popular in herbal formulas marketed for calming effects.

Scientific studies on California poppy are limited and largely preclinical, but some evidence suggests it may exert mild sedative and anxiolytic (anxiety-reducing) effects. The plant contains a range of alkaloids (such as californidine and protopine) believed to interact with GABAergic and other neurotransmitter systems, which could explain its calming properties. However, robust clinical trials in humans are scarce, and most data come from animal studies or small, preliminary human trials often in combination with other herbs (such as valerian).

In summary, while California poppy’s use for tension is rooted in traditional medicine and supported by some pharmacological rationale, the scientific evidence base is weak. It is considered safe for short-term use in adults, but more rigorous studies are needed to confirm its efficacy for tension.
