Cleaver is actually quite a useful herb. I am making a tincture of the dried leaves right now. From
https://altnature.com/gallery/..., here is what it does.
It is used both internally and externally in the treatment of a wide range of ailments. . A valuable diuretic, it is often taken to treat skin problems such as seborrhoea, eczema and psoriasis, and as a general detoxifying agent in serious illnesses such as cancer. It has a mild laxative effect and stimulates the lymphatic system and has shown benefit in skin related problems. The fresh plant or juice of Cleavers herb is used as a medicinal poultice for wounds, ulcers and many other skin problems. An infusion has shown of benefit in the treatment of glandular fever, tonsilitis, hepatitis and cystitis. The infusion is also used to treat liver, bladder and urinary problems.
The dried or fresh herb is alterative, anti-inflammatory, antiphlogistic, aperient, astringent, depurative, diaphoretic, diuretic, febrifuge, tonic and vulnerary. The plant contains the valuable constituent asperuloside, a substance that is converted into prostaglandins by the body. Prostaglandins are hormone-like compounds that stimulate the uterus and affect blood vessels. Much more scientific research is being done on the plant it is of great interest to the pharmaceutical industry.
