Apothecary's bouquet

Three therapeutic plants in bloom now.
 Lungwort's speckled foliage was formerly taken to signify a connection with lung disease and so the plant was used to treat respiratory disorders. Sure enough, its mucilaginous quality has been found to provide relief for coughs and sore throats.
Yellow archangel was employed as an astringent and  recommended by Nicholas Culpeper for treating old, filthy, corrupt sores and ulcers, yea, although they grow to be hollow, and  to dissolve tumours.
Finally the white-flowered Scurvy-grass is, as its name suggests, an anti-scorbutic. Growing on the coast, its leaves was sought by Vitamin C-deprived sailors  coming ashore after long sea voyages. Nowadays it's the one doing the travelling since its affinity for saline soil means the plant is spreading along major roads that have been salted to prevent icing in the winter. A kind of herbal tit for tat.
