Perceived Changes in Anxiety Symptom Burden During Treatment With Bryophyllum Pinnatum and Tolerability

Summary

Bryophyllum pinnatum (BP) is a succulent perennial plant from the family Crassulacea (for reviews see Fürer 2016 and Hamburger 2017). Leaf extracts from BP have been used in traditional medicine to treat wounds and ulcers, skin diseases, infections, inflammations, pain, diabetes, hypertension, and cancer. In Europe, BP started to be used at the beginning of the 20th century in Anthroposophic medicine, a form of holistic medicine with an integrative approach. Almost a hundred years later, BP preparations are still often prescribed in Anthroposophic medicine, where it is used in the treatment of a broad spectrum of diagnoses, most often of mental and behavioural disorders (ICD-10 F00-F99), including anxiety, depressive, and sleep disorders (Simões-Wüst 2012). In Switzerland, during the last decade, BP (50 % tablets) started to be used in conventional settings mainly in the treatment of preterm labour (Simões-Wüst 2018, Plangger 2006), overactive bladder (Betschart 2013), sleep disorders (Simões-Wüst 2015), and restless legs syndrome (Von Manitius 2019). Whereas the good effectiveness of BP preparations in the treatment of preterm contractions and overactive bladder is well supported by data obtained using a variety of in vitro models (see e.g. Santos 2018, Bachmann 2017, Simões-Wüst 2010), less is known about possible mechanisms of action that would support their use in the treatment of mental and behavioural disorders. Nevertheless, the observed improvements of sleep disorders are corroborated by animal experiments showing that different fractions of the leaf extract of BP can prolong the pentobarbitone-induced sleeping time (Yemitan 2005 and Pal 1999), indicating a CNS depressant action. Some of the bufadienolides present in Bryophyllum species are thought to be responsible for the sedative effects (Wagner 1986). The aim of the present study is to find out if patients suffering from anxiety symptoms perceive improvements of these symptoms during treatment with Bryophyllum 50% tablets. Since anxiety symptoms are often related to depression, reduced sleep quality, stress, reduced health-related quality of life and the feeling of not being able to control owns life (internal coherence), these aspects will be assessed as well.
