Calendula officinalis is packed with antioxidant, antifungal and antimicrobial properties, which makes it a perfect companion for detoxes. Its anti-inflammatory properties can also help with sore throats and stomach flues. Tinctures are a food supplement with healing properties, not a medicine. If you have serious issues you need treating, contact your GP. Dosage: 20 - 40 drops are diluted in a bit of water and taken once to three times a day. For cleaning sore throats, dilute 40 - 60 drops in water, gargle and discard.
