Angelica sinensis Processes Antiplatelet Therapy

By Kyle J. Norton

Antiplatelet activity is a process that prevents and treats blood clots.

Platelets are tiny blood cells that protect the other to prevent injury and infection by forming clots to stop bleeding.

Platelets are made in the bone marrow that also produces white and red blood cells.

Platelet aggregation refers to the platelet-to-platelet adhesion in the blood that forms a clot.

Platelet aggregation plays a critical role in the protection of the body against blood loss due to injury or tissue damage.

However, activated platelets that stimulate blood clot formation have also been found to induce atherothrombotic disease. 

Antiplatelet aggregation medicines, also known as a platelet agglutination inhibitor are the types of medicine that process blood thinning property.

In other words, antiplatelet aggregation medicines reduce the risk of blood clotting used in patients who have a high risk of cardiovascular disease such as aspirin.

Coagulation disorders or bleeding disorders are medical conditions that affect blood clotting activities. 

The most common diseases associated with coagulation disorders are Hemophilia, Von Willebrand disease, clotting factor deficiencies, hypercoagulable states, and deep venous thrombosis.

The most common causes of bleeding disorders are found in patients with a lower red blood cell count and vitamin K deficiency.

However, long-term use of certain medications has also been found in the side effects of bleeding disorder.

On finding a natural ingredient for the prevention and treatment of cardiovascular diseases, scientists examined the antiplatelet activity of 4 traditional Chinese medicine (TCM) herbs effective for prevention cardiovascular diseases, namely Radix Salvia Miltiorrhiza (Red sage root, Danshen), Radix Pueraria Lobata (Kudzu root, Gegen), Radix Angelica Sinensis (Angelica root, Danggui), and Rhizoma Ligusticum chuanxiong (Szechuan lovage rhizome, Chuanxiong).

Angelica or Dang Qui is a herb of Genus Angelica from the family Apiaceae, indigenous to China.

The herb has been used as a Queen herb in traditional Chinese medicine antispasmodic and vasodilatory agent, and to balance the hormones in women for a normal menstrual cycle and menstruation and strengthen heart, spleen, kidneys, and liver for both men and women, etc. In other words, it is used to treat gynecological ailments, fatigue, mild anemia, and high blood pressure. It has analgesic, anti-inflammatory, etc.

Selected Sprague-Dawley rats treatment groups which were received a bolus oral dose of DAPT on day 1 followed by DAPT for consecutive 13 days in absence and presence of orally co-administered four TCM herbs (Danshen, Gegen, Danggui and Chuanxiong) at their low and high doses.

According to the experimental results
* Co-administration of Gegen and Danggui significantly altered the pharmacokinetics of ASA and CLP in DAPT with increased systemic exposure of ASA and CLP respectively.

* All co-administered herbs, significant inhibition on rCyp2c11 and carboxylesterase activities associated with the hydrolysis of some drugs to inactive metabolites, particularly, for DAPT with Danshen, Gegen and Danggui co-treatment.

* All the treatments did not cause detectable changes in COX (associated with inflammation_ and P2Y12 mRNA (associated with platelet formation and protein expressions.

Based on the results, researchers suggest, "Among the four studied TCMs, it was demonstrated that co-administration of Gegen and Danggui could lead to altered pharmacokinetics of DAPT with significant inhibition on rCyp2c11 and carboxylesterase activities. Although Gegen, Danggui, and Chuanxiong might potentially offset the anticoagulant activity of DAPT, the overall pharmacodynamics outcome was not considered to be harmful due to a lack of risk in bleeding".

Taken altogether, Dandelion may be considered an anti-platelet activity, pending to the confirmation of the larger sample size and multicenter human study.
