Lungwort (Pulmonaria officinalis) - the spotted spring plant
- Lungwort (Pulmonaria officinalis L.) is a perennial plant of the borage family (Boraginaceae), native to Central and Eastern Europe. It is recognisable by its white-spotted leaves and its flowers, which change colour from pink to blue-violet in spring.
- The herb mainly contains phenolic acids - above all rosmarinic acid and other caffeic acid compounds such as lithospermic and salvianolic acids - as well as flavonoids, mucilage, tannins and silicic acid. LC-MS/MS analyses of the aerial parts identified 45 phenolic compounds (Krzyżanowska-Kowalczyk et al., 2018).
- The name comes from the medieval doctrine of signatures: the spotted leaves were thought to resemble lung tissue (Latin pulmo = lung). Hildegard of Bingen already described the plant as "Lungwurz" in her Physica around 1150.
Lungwort extract 10:1 - concentrated instead of simply ground
- Green Naturals lungwort capsules contain a 10:1 extract with 300 mg per daily dose - mathematically obtained from 3,000 mg of dried herb. By comparison, many manufacturers only use ground lungwort powder without stating an extract ratio.
- Plant species and plant part are clearly declared: Pulmonaria officinalis, aerial parts - compared to many suppliers who only state "lungwort" without the botanical species. This matters because the lichen tree lungwort (Lobaria pulmonaria) is also colloquially called lungwort.
- The phenolic acid fraction of Pulmonaria officinalis has been investigated in vitro in human blood plasma (Krzyżanowska-Kowalczyk et al., 2021); a recent review summarises the known plant compounds of the genus Pulmonaria (Chauhan et al., 2022).
Lungwort capsules - clearly dosed, vegan, lab-tested
- One capsule a day provides 300 mg of lungwort extract - always the same amount, without weighing or brewing tea. There are currently no authorised health claims under EFSA for lungwort - which is why we deliberately make no claims about effects.
- The formula consists of just three ingredients: lungwort extract, rice flour as a natural carrier and a plant-based HPMC capsule shell - vegan, gelatine-free and without artificial additives.
- 60 vegan capsules per tub last 60 days - a 2-month supply, manufactured and lab-tested in Austria.
-
Best time to take
Take 1 capsule daily with sufficient liquid, for example in the morning with breakfast. You can choose the time individually - what matters is taking it regularly every day.
-
