Harvesting Guidelines
The optimal time for harvesting cleavers varies according to different herbal traditions. Some recommend harvesting the plant when it is in full bloom, but before seeds have formed, while others prefer waiting until the plant begins to bloom and the seeds start to form. There is also a practice of gathering cleavers before flowering begins. Regardless of the timing, it is important to dry the herb immediately after harvesting. Turn the herb regularly during the drying process to ensure proper airflow and prevent blackening, which could diminish its quality and potency.
Cleavers, also known as Galium aparine, is a popular herb among herbalists for its medicinal properties, particularly its support for the lymphatic system. Known for its refreshing and cleansing qualities, it has been used for centuries to aid in detoxification and promote overall health. The herb is especially beneficial for the urinary and genito-urinary systems, supporting healthy urinary function and offering relief from various skin conditions.
Medicinal Uses and Benefits
Cleavers is renowned for its lymphatic support and is often used to detoxify the body, promoting lymphatic drainage and aiding the removal of toxins. Its cooling and refreshing properties make it an excellent herb for the spring months when it is traditionally believed to clear stagnation and prepare the body for warmer weather. Cleavers is considered a safe herb for children and can be taken daily as a gentle tonic to nourish and build the body.
The herb is also known for its ability to combat inflammation, especially in cases of enlarged lymph nodes. When a lymph node becomes swollen, cleavers may help reduce inflammation due to its cooling and soothing nature. It is a gentle herb that is particularly beneficial for individuals with Vata constitution—those who tend to be thin, dry, and nervous.
In addition to its lymphatic actions, cleavers is supportive of various skin conditions, including eczema, psoriasis, scrofula, and scurvy, due to its astringent and detoxifying properties. It is also used in the treatment of burns, as it helps cool and heal the skin.
Scientific Studies and Modern Research
While scientific studies on cleavers are still limited, its benefits are supported by its historical use and modern research into its properties. Studies have identified cleavers as a lymphatic stimulant, with its ability to enhance detoxification and reduce inflammation being key. It has been shown to have diuretic effects, which may help in flushing toxins from the body.
Moreover, clinical trials investigating cleavers' role in cancer prevention and treatment have provided mixed results. Some studies suggest that cleavers could have an anti-tumoral effect, which has led to its inclusion in experimental herbal therapies for conditions like BPH (benign prostatic hyperplasia).
A study published in the Journal of Ethnopharmacology (2014) examined its antioxidant properties and confirmed that it could be beneficial for general detoxification. However, more research is needed to confirm its effectiveness in cancer therapies.
