Palo Azul

Comes from the Chaco region, the highly rare wild herb "Palo Azul"

Palo Azul is one of the very rare natural herbs found in the Chaco region of Paraguay, South America, which is called an herb mine, and it is traditionally consumed by the native people as extracted tea.

Palo Azul means "blue twig" Palo Azul comes from Paraguay

In general, herbs that are grown in a harsher natural environment contain many nutritional components by sufficiently absorbing the blessings of nature.

Due to the great difference between warm and cold temperature in the Chaco region, the soil contains highly concentrated mineral components. However, at the same time, only a small number of plant species can be spontaneously grown. Palo Azul gives white flowers even in such a harsh environment and thus, it is considered one of the "wild" herbs that are ranked "the most precious species".

The land, which is almost untouched by humans, is free from any pesticides at all. By limiting the areas where the raw material herb can be collected, we assure the reliability of the traceability of each lot.

Evidence of Palo Azul
Main components of Palo Azul

The effectiveness has been confirmed by conducting researches actively in cooperation with various research institutes and clinics in Japan, with a focus on open human clinical trials. We are presently conducting collaborative studies mainly with university research laboratories to further understand the action mechanism.

Anti-glycation effect of Palo Azul

Glycation is a reaction (Maillard reaction) that turns brown mainly by combining sugar and protein, and it is also an important element related to taste in food.

However, when a glycation reaction occurs in the body, an aging substance called AGEs (final product of glycation) is produced and accumulated in various sites, which leads to systemic aging.

Because oxidation and glycation are related like two sides of a coin, it is important to prevent not only oxidation but also glycation simultaneously to prevent aging. Palo Azul supports not only glycation reaction but also general glycation stress reaction widely.

Palo Azul copes with glycation stress

<Effect of inhibition of glycation end products of Palo Azul extract>

It was found that Palo Azul extract powder has 3DG production inhibitory action, pentosidine production inhibitory action and CML production inhibitory action. Furthermore, regarding 3DG and CML. Palo Azul extract powder shows higher inhibition rate than aminoguanidine (*).

*Aminoguanidine: A typical AGEs production inhibitor, which is a therapeutic drug for diabetic complications (not approved in Japan)

There is no measured value for pentosidine because no positive control is set.
