Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A past study showed that among Anthroposophical physicians the most frequent diagnosis group where BP preparations are prescribed are mental and behavioural disorders such as anxiety and sleep disorders. In the present study, we, therefore, want to investigate the effectiveness of Bryophyllum tablets in patients with anxiety symptoms.
Study participants will be recruited among the patients on the waiting list of the Department of Psychiatry and Psychosomatics at the Clinic Arlesheim.
* Participant recruitment will continue until 60 patients have concluded the study.
* Recruitment period will probably last 15 months.
* Duration of the drug administration is 3 weeks.
Participants will fill in a questionnaire three times. At baseline, after two and after three weeks of Bryophyllum intake.

Bryophyllum pinnatum 50% chewing tablets
Bryophyllum is administered for 3 weeks. Bryophyllum is given in form of chewing tablets, 350mg per tablet, 0-2-2-2/d: 2 tablets at midday, 2 tablets in the evening, 2 tablets before bedtime.
Bryophyllum 50 % Chewing Tablets
Each 350 mg tablet corresponds to 170 mg of leave press juice from Bryophyllum pinnatum, dried down to 17 mg by mixing with lactose; 100 mg dried BP matter in 1 g.
