[Improvement of Stress Resistance and Quality of Life of Adults with Nervous Restlessness after Treatment with a Passion Flower Dry Extract].

[Article in German]

Abstract

BACKGROUND:

The passion flower dried ethanolic extract investigated in this non-interventional study has well-documented calmative effects and good tolerability. We investigated the effects of this extract on the stress resistance (resilience) and quality of life (QoL) of patients suffering from nervous restlessness. The addiction potential of the drug and the course of symptoms were also evaluated.

METHODS:

Adult patients aged ≤ 95 years with the diagnosis 'nervous restlessness' were treated for 12 weeks with a dried ethanolic extract of passion flower (Passiflora incarnata L.). Standardized questionnaires were used to evaluate the resilience (RS-13), QoL (EQ-5D including EQ-VAS), and the addiction potential (BDEPQ).

RESULTS:

After 12 weeks of treatment, significant (p < 0.001) improvements were measured in the patients' resilience (RS-13: from 52.1 to 67.7 points) and QoL (EQ-VAS: from 47.9 to 75.0 points). Also, the mean BDEPQ score was significantly (p < 0.001) reduced (from 23.0 to 19.3 points). The mean values of all accompanying symptoms (inner restlessness, sleep disturbance, exhaustion, fear, lack of concentration, transpiration, nausea, trembling, and palpitation) improved significantly (p < 0.001). Tolerability of treatment was rated as 'very good' or 'good' by the majority of the patients. Three cases of mild adverse events (tiredness) were reported.

CONCLUSION:

The passion flower extract investigated in the present study appears to be effective in improving resilience and QoL in patients suffering from nervous restlessness and is well tolerated.
