Uncaria sinensis

Why You Need It

• Calms the Nervous System: It acts as a natural sedative, helping to reduce anxiety and promote a sense of tranquility.
• Lowers Blood Pressure: It has demonstrated antihypertensive properties, helping to relax blood vessel walls.
• Relieves Muscle Tension: It is a potent antispasmodic, meaning it helps stop involuntary muscle twitching and cramping.
• Reduces Dizziness: In TCM, it is the go-to herb for 'wind' symptoms, such as vertigo and headaches.

Deep Dive

Uncaria sinensis contains active compounds called oxindole alkaloids (specifically rhynchophylline and isorhynchophylline). These compounds are the heavy lifters here. They work by blocking calcium channels in your blood vessels and muscles.

Imagine your blood vessels are hoses. When you are stressed, they kink and the pressure builds (high blood pressure). These alkaloids unkink the hose, allowing blood to flow smoothly and pressure to drop. Furthermore, they inhibit the release of excitatory neurotransmitters in the brain, which is why it helps quiet a 'noisy' mind and relaxes tight muscles. It is a gentle, non-addictive alternative to pharmaceutical muscle relaxants.

Natural Food Sources

Unlike Vitamin C found in oranges, Uncaria sinensis is not a food. It is a dried vine bark/herb. You will not find it in the produce aisle. It is consumed as a tea or a decoction (a concentrated liquid boiled from the herb).

However, to support the functions it aids (relaxation and blood pressure), you can incorporate these foods:

Supplementation

• Usage: Usually found in capsule form (extracts) or dried cut vine for tea.
• Dosage: Standard clinical doses range from 3g to 15g of the crude herb daily. For extracts, follow manufacturer guidelines, typically 300-500mg.
• Who Should Take It: Ideal for those with Type A personalities, high stress, tension headaches, or mild hypertension.
• Best Time: Evening, as it can cause drowsiness.
