CARQUEJA
Baccharis Trimera

The bright green leafy stalks of Carqueja have a succulent consistency. This perennial green herb has a lovely yellowish-orange flowers at the top of the plant.

Common Names:
Carqueja, cacalia amara, cuchi-cuchi,
quinsu-cucho, Carqueja-do-mato

Part used:
Leaf, aerial parts.

Description and Habitat: 
Carqueja is a shrub-like perennial green plant that grows in many terrains of South America. It grows in dry highlands, rocky grounds, sandy fields, riverbanks and swampy areas throughout the Amazon Rainforest in Peru, Brazil and Columbia as well as tropical parts of Argentina, Paraguay and Uruguay. Carqueja does not have leaves or stems; instead, it has bi-winged or tri-winged branches that are leaf-like and fulfill photosynthetic functions. Yellowish-orange flowers are scattered along the stalks and tend to accumulate at the top. The whole plant can reach up to four feet high, though it is commonly two to three feet high.

Indigenous Traditional Use: 
Carqueja has been used by Indigenous People for centuries for stamina as well as for fertility in women and virility in men. From a therapeutic standpoint, Carqueja has been used for a wide variety of ailments pertaining to the digestive system for which it is considered rather effective. For example, natives would use Carqueja to strengthen the digestive process, eliminate intestinal parasites, stop diarrhea and to ease irritation of the digestive system after an episode of indigestion, diarrhea or food poisoning. However, the main use of Carqueja is for supporting the liver. Natives would use it to alleviate various liver dysfunctions, to purge the liver, to eliminate obstructions of the gall bladder and as a blood cleanser. Natives were also reported to use Carqueja for reducing fever and for alleviating inflammatory conditions.

The traditional use consisted of infusing a good amount of dried Carqueja into one liter of water, which was drunk throughout the day. People would also chew on the fresh fleshy stalk.

Scientific Studies – Mechanism of Action
Flavonoids have been isolated from Carqueja that were shown to protect the liver against toxins. In this scientific work, the mechanism of action has not been explained. However, flavonoids have been shown to protect against liver toxicity by binding to toxins and preventing their absorption. For example, silymarin, a flavonoid that is common to green plants and which is present in milk thistle and in blue-green algae, was shown to offer 100% protection against several liver toxins. Likewise chlorophyll,though it is not a flavonoid, was shown to offer significant protection against the most potent liver carcinogen, aflatoxin.

In a study performed on mice, pretreatment with Carqueja significantly reduced inflammation and pain in several models of inflammation. Carqueja also reduced intestinal contraction, which supports its soothing effect in cases of irritation of the digestive system. Carqueja also prevented the development of ulcers, which may be linked to its anti-inflammatory properties. All these benefits may be linked to the ability of Carqueja to inhibit prostaglandin biosynthesis due to some prostaglandins being inflammatory compounds. Since prostaglandins are also mediators of pain and fever, this data may support the indigenous use of Carqueja for reducing fever.

More recently, compounds were isolated from Carqueja that had the ability to reduce calcium flow in smooth muscles and relax vascular smooth muscles in rats. In brief, the arteries of the body are surrounded with smooth muscles whose purposeis to control blood pressure by contracting (increasing blood pressure) or relaxing (reducing blood pressure). The internal signal for a smooth muscle to contract is an inflow of calcium within the smooth muscle cells. This inflow of calcium can be triggered by a variety of signals and common drugs for the treatment of high blood pressure aimed at reducing calcium inflow into smooth cells. Therefore, pending more studies, Carqueja could be an auxillary natural approachto address the challenges associated with hypertension.
