“Sundew has antimicrobial and antibacterial properties and is an important herb for the respiratory tract. It is a soothing remedy for whooping cough, asthma, chronic bronchitis, and dry, irritating coughs and is reported to have a relaxing effect on the bronchial tree. Some herbalists ascribe rejuvenative and longevity properties to this herb. Fresh juice of sundew is also used externally against warts and corns.
Sundew has a taste of ACRID and a temperature of COOL.”
Historical Uses
Sundew has been used in traditional European herbal medicine since the Renaissance. It was primarily employed as a remedy for respiratory ailments, including coughs, bronchitis, whooping cough, and tuberculosis. The plant’s mucilage was believed to soothe inflammation and act as an expectorant.
Modern Clinical Uses by Herbalists and Naturopaths
Herbalists and naturopaths still value sundew for its potential effects on respiratory health. It is included in remedies for dry, spasmodic coughs and other bronchial conditions. In homeopathy, Drosera preparations are used for similar indications.
Chemistry
Sundew contains several bioactive compounds, including:
- Naphthoquinones: Plumbagin and related compounds, which have antimicrobial, antifungal, and anti-inflammatory properties.
- Flavonoids: Antioxidant compounds such as quercetin.
- Tannins: Astringent agents that contribute to the plant’s healing properties.
- Mucilage: Sticky polysaccharides aiding in soothing irritation.
Pharmacology
- Anti-inflammatory: Plumbagin and flavonoids reduce inflammation by inhibiting pro-inflammatory enzymes.
- Antimicrobial: Active against some bacteria and fungi, potentially supporting respiratory health.
- Antispasmodic: May reduce spasms in smooth muscle, especially in the respiratory tract.
- Antioxidant: Flavonoids neutralize oxidative stress.
Clinical Trials
- Research on sundew’s clinical efficacy is limited, with most studies focused on its chemistry and preclinical models.
- Respiratory Health: Studies suggest antitussive effects in laboratory settings, but robust clinical trials are lacking.
- Antimicrobial Activity: Some studies have demonstrated activity against pathogens like Staphylococcus aureus.
- Future research is needed to establish its efficacy, safety, and mechanisms in clinical settings.
Summary
Sundew remains a valuable plant in traditional and modern herbalism, particularly for respiratory health. Its pharmacological properties suggest promise, but clinical validation is needed to confirm its therapeutic potential. Use with professional guidance for safe application.
