    Justification

    The species is widespread and while it is possibly declining in parts of its range, it is not thought that any global population decline is likely to meet (or be close to meeting) the threshold for Vulnerable. Therefore the species is assessed as Least Concern.

    Description

    The species is classed as globally 'Secure' by NatureServe (2014), however the populations in some states in the USA and Provinces in Canada are classed as 'Critically Imperiled', 'Imperiled' or 'Vulnerable'. The Canadian Endangered Species Conservation Council (CESCC 2011+) also class the species as 'Secure (for Canada only).

    Use and Trade

    This species is used as an ornamental plant although its well known for its medicinal properties, having been popular for its fortifying and aphrodisiac effects. It relaxes the muscles of the respiratory tract, easing breathing and relieving wheezing and so is of great value in the treatment of various chest complaints. The flowering plant is antibacterial, antibiotic, antispasmodic, antitussive, demulcent, expectorant and hypoglycaemic.The entire fresh plant, harvested when it is starting to flower, is used to make a homeopathic remedy. It is used mainly in the treatment of coughs and is specific for whooping cough (TAN QG et al.,2009).
