Uncaria sinensis, commonly called Guan Zhi in Chinese, has been a staple of East Asian herbal medicine for more than a millennium. The Chinese Pharmacopoeia 2020 records that the dried root bark is boiled to produce a decoction that lowers high blood pressure and calms the nervous system. In Vietnam, the Traditional Medicine Monograph 2018 notes that an infusion of the same root bark is brewed as a tea to aid stroke recovery and relieve headaches. The Korean Pharmacopoeia 2019 lists a tincture made from the root bark that is applied topically as a poultice to reduce swelling and bruising. All of these preparations use the root bark, the most potent part of the plant, and are made by infusing, decocting, or macerating the dried material in water or alcohol.

A simple and safe way to enjoy the benefits of Uncaria sinensis is to make a mild tea. Take 5 g of dried root bark, place it in a pot with 250 ml of boiling water, cover, and let it steep for 10 minutes. Strain the liquid, cool slightly, and drink two cups per day. This dose is well below the 10 g per day limit recommended in the Chinese Pharmacopoeia. Pregnant or nursing women should avoid the tea because the alkaloids may stimulate uterine contractions. If you have kidney disease or are taking antihypertensive drugs, consult a healthcare professional before using the tea.

The medicinal effects of Uncaria sinensis are largely attributed to a group of indole alkaloids that have been isolated from the root bark. Rhynchophylline and isorhynchophylline are the most studied compounds; they relax blood vessels and protect nerve cells, which explains the plant’s traditional use for hypertension and stroke. Other alkaloids such as corynoxine, hirsutine, and hirsutidine also contribute to the calming, anti‑inflammatory, and neuroprotective properties reported in the pharmacopoeias.

Today, researchers are testing standardized extracts of Uncaria sinensis in clinical trials for hypertension and neuroprotection, and several herbal supplement companies offer products that contain the root bark extract. Traditional use continues in rural communities in China, Vietnam, and Korea, where the plant is still harvested from the wild and prepared by hand. The combination of ancient wisdom and modern science keeps Uncaria sinensis a valuable resource for both practitioners and consumers, and its availability in health‑food stores and online markets makes it accessible to anyone interested in natural approaches to blood‑pressure management and brain health.
