Higher Nature Citricidal Grapefruit Seed Extract 25ml is a popular, multi-purpose liquid formula made from grapefruit seed and pulp, containing a potent concentrate (typically 19-34% extract). The formula is glycerine-based for a gentle taste and is naturally rich in antioxidants and essential oils, known for their anti-bacterial, anti-microbial, and anti-fungal properties. Ideal for a natural first aid kit and for travelers, Citricidal is highly versatile. It can be taken internally, always diluted, as a food supplement to support digestive health and overall wellness. Externally, it serves as an all-round home remedy, useful as a mouthwash or gargle, a facial cleanser (safe for acne and normal skin), a scalp treatment (for issues like dandruff), and a topical rinse for nails and minor skin irritations. **Warning: This product must always be diluted before use and should never be applied full strength to the mouth, eyes, or skin.** Adults typically mix 5-10 drops in at least 100ml of water or juice and consume 1-3 times daily.
