( Dried, wildcrafted rhizome )
Code KUT01 -- Price: $7.50
60 Capsules x 500 mg.
-- is an old ayurvedic "bitter," native to the Himalayan mountains
(primarily from Jammu / Kashmir to Sikkim in northern India).
Its bitter principles comes from the irioid glycosides known as
picroside I and picroside II (the latter also known as "kutkoside") .
Combined, the resulting combination is known as kutkin or picroliv.
These are its known active components. 1
Uses & Protocols
Studies show that you need no more than
about 25 mg.of picroside I and II for the product to be effective. We recommend that you
take one capsule, twice a day, to get more than this "effective amount." If you're not
taking Kutki as a "maintenance supplement," and, instead, are dealing with a medical
challenge (i.e. hepatitis), you may double the dosage to two capsules, twice a day.
None when taken as directed.
If you have any questions, please write to us at: email@example.com.

Anti-inflammatory effects of Chinese medicinal herbs on cerebral ischemia (2011)
Comment: Discusses the role of apocynin, a primary, active medicinal components
of kutki in blocking "microglia activation in a chemical ischemic model of cultured neuroblastoma cells."
A Picrorhiza kurroa derivative, picroliv, attenuates the development of dextran-sulfate-sodium-induced colitis in mice. (2012)
Although this study was conducted with mice, it supports the traditional use of kutki to treat intestinal issues.
One of the most important findings in this study: "Singh et al. investigated the effect and role of picroliv in
an ex vivo rat aorta ring model of angiogenesis and punch wound healing. Picroliv treatment not only enhanced the sprouting
and migration of endothelial cells but also showed improved re-epithelialization, neovascularization, and migration of
various cells such as endothelial, dermal myofibroblasts and fibroblasts into the wound bed."

Natural Compounds as Modulators of NADPH Oxidases (2013)
Comments: Of particular relevance was this passage: "Later studies involved apocynin,
a naturally occurring NADPH oxidase inhibitor originally isolated from the roots of Picrorhiza kurroa. Apocynin cannot
be used as selective NADPH oxidase inhibitor due to its direct antioxidant and several off-target effects .
Apocynin is an orally active agent that can block NADPH oxidase assembly in membrane but requires a reaction
with peroxidase for its activation, and therefore does not work immediately . Apocynin reduces ROS production
in models of arthritis, asthma, and hypertension, abolishing the increase in vascular O2 •− and preventing endothelial
dysfunction . However, effects of apocynin are not specific, as it has been reported to affect arachidonic acid metabolism ,
to increase glutathione synthesis, and to activate the AP-1 transcription factor . In addition, it has recently been shown
to be a direct ROS scavenger in certain experimental conditions .

Scutellaria baicalensis, Bupleurum falcatum, Phyllanthus species, Berberis aristata, Picrorhiza kurroa,

The Impact of Environmental Factors in Influencing Epigenetics Related to Oxidative States in the Cardiovascular System (2017)
Important Excerpt: Notably, the Mediterranean dietary habit stands out as it is mainly based on natural antioxidant
ingredients . Its combination with an active lifestyle has been successfully associated with reduced rates of CVD in the
corresponding populations . It is still arduous to comprehend whether the beneficial outcome of natural antioxidants in
plant-derived food on the cardiovascular circuit is more related to a systemic rebalance of the oxidative states rather than
a selective effect. However, strong evidence is supporting this latter hypothesis. For instance, apocynin
(4-hydroxy-3-methoxy-acetophenone), extracted from the root of Picrorhiza kurroa (Kutki), is a well-recognized antioxidant ,
described to prevent excessive collagen deposition and cardiomyocyte apoptosis in rats .
