Our bodies can be in states of health, illness, and sub-health. For instance, blockage in the body is an unhealthy state that manifests as cold hands and feet, decreased memory, and easy formation of moles on the body. When this occurs, it is important to take notice and promptly clear the blockage to restore the body to a state of unobstructed flow.

What are the symptoms of blockage in the body?

1. Cold Hands and Feet: When blood circulation in the body is obstructed, blood and oxygen cannot quickly reach the extremities. As a result, the limbs lack the nourishment of blood and oxygen. The body's temperature is regulated by qi and blood, and people with insufficient qi and blood are more prone to having cold hands and feet. The reasons for insufficient qi and blood are often related to obstructed meridians in the body. Therefore, for these individuals, the first step to replenishing qi and blood is to regulate their meridians and ensure their smooth flow, which is conducive to the circulation of qi and blood.

2. Decreased Memory: When there is blockage in the qi and blood of the body, blood circulation gradually decreases, leading to the inability to excrete toxins and waste from the body. This situation can also affect the functioning of the brain, as the brain's nerves are unable to receive the nourishment of oxygen and blood. Over time, this can lead to decreased memory.

3. Easy Formation of Moles: As people age, they may develop moles on their bodies. These moles are caused by an excess of toxins and waste in the body, resulting in pigmentation on the skin surface. The reasons for pigmentation are related to both an excess of toxins and waste in the body and obstructed blood circulation. To prevent the formation of more moles, it is important to improve internal circulation and maintain smooth flow of qi and blood in the body.

How to Determine the Degree of Blockage in the Body?

Our bodies have a "window" that can help us visually assess the degree of blockage, which is the "sublingual venous vessel," known as "sublingual collateral vessels" in traditional Chinese medicine. Nowadays, traditional Chinese medicine has formed a theory of "collateral vessels" and established a society dedicated to its study. Pathological changes in sublingual collateral vessels are mainly manifested in two aspects: color and morphology. A dark purple color and thick or dilated shape of the sublingual veins suggest qi stagnation and blood stasis or a combination of phlegm and blood stasis. A light purple color and enlarged or dilated veins indicate cold stagnation or qi deficiency with blood stasis. A reddish purple color and dilated veins suggest heat accumulation with blood stagnation, while a light red or light blue color and small veins indicate a weak constitution. Changes in the sublingual collateral vessels primarily indicate the presence of blood stasis lesions. Based on their colors ranging from dark purple, light purple, to reddish purple, we can identify the underlying causes of blood stasis as qi stagnation, cold stagnation, qi deficiency, or heat accumulation.
