Description

Japanese knotweed - 50/100 ml

Our high-quality Japanese knotweed tincture is a carefully crafted herbal extract. We extract it from the root of Japanese knotweed (Polygonum cuspidatum), which comes from certified organic cultivation. The root of Japanese knotweed has been mentioned in Asian sources for centuries and is part of traditional herbal medicine there.

This natural product from Sagrusan is a versatile companion. If you’re looking to buy high-quality Japanese knotweed tinctures, you’re choosing a plant that is used particularly in Traditional Chinese Medicine (TCM). As a liquid extract, the tincture is a practical alternative to capsules or powder and can be easily incorporated into your daily routine.

Japanese knotweed – A portrait of the plant

Botanical name:
Reynoutria japonica (synonym: Polygonum cuspidatum)

Common names:
Kamchatka knotweed, Japanese knotweed, giant knotweed

Brief description of the plant:
Japanese knotweed is a large, perennial, herbaceous plant native to East Asia. In Europe, it is considered an invasive neophyte because it spreads very rapidly. The plant can reach a height of up to three meters and forms hollow, bamboo-like stems. Its roots (rhizomes) are robust and can extend deep into the soil.

Special features:
The plant is a true survival expert: Reynoutria japonica can regrow completely from tiny root fragments just a few millimeters long—even after years buried in the soil. This regenerative power makes it a fascinating example of botanical resilience.

History and traditional significance of Ground-ivy Tincture

In its native Asia, particularly in China and Japan, Japanese knotweed has been an integral part of traditional herbal medicine (TCM) for centuries. There, the root, known as “Hu Zhang,” is used in various preparations thanks to its diverse properties.

Key Ingredients of Japanese knotweed (factual)

The root of Japanese knotweed is particularly rich in phytochemicals. The best-known compounds are:

Resveratrol (particularly trans-resveratrol)
Anthraquinones
Flavonoids

The content of these compounds is subject to natural fluctuations.

Why Japanese knotweed as a tincture?

The tincture preserves the soluble compounds of Japanese knotweed in concentrated form and keeps them available over a long period of time. Alcohol serves as a natural solvent to extract the spectrum of water- and fat-soluble plant compounds from the root. Absorbed through the oral mucosa, the active ingredients are made directly available to the body without relying solely on the digestive tract. This makes the tincture a practical and flexible addition to your daily routine.
