How to Get the Larval Tear
Larval tears, also known as “tears of the worm,” are a rare and valuable ingredient in traditional Chinese medicine. These tears are secreted by the larvae of the silkworm, Bombyx mori, during the pupal stage. They are believed to possess various therapeutic properties, including the ability to nourish the liver, improve eyesight, and enhance the immune system. In this article, we will explore the process of how to obtain larval tears and the significance of this precious substance.
The first step in obtaining larval tears is to raise silkworms. Silkworms are reared on mulberry leaves, which provide them with the necessary nutrients to produce the silk and, subsequently, the larval tears. To start, purchase a batch of silkworm eggs and prepare a suitable environment for them to hatch. This includes providing a warm and humid environment with sufficient ventilation.
Once the silkworms have hatched, they will go through several stages of growth, known as instars. During this time, they will consume large amounts of mulberry leaves and produce silk. After about four to five instars, the silkworms will reach the fifth instar, which is the final growth stage before pupation.
The next step is to induce pupation. This can be achieved by stopping the supply of mulberry leaves to the silkworms. As a result, the silkworms will enter the pupal stage, during which they will produce larval tears. The pupal stage typically lasts for about two weeks.
To collect the larval tears, place the pupae in a clean and sterile container. As the silkworms pupate, they will secrete the tears onto the pupal case. Gently tap the case to release the tears into a small container. It is important to ensure that the collection process is hygienic to avoid contamination.
Once the tears have been collected, they can be stored in a cool, dry place. However, it is essential to note that larval tears are highly perishable and should be used within a short period. They can be used directly in traditional Chinese medicine formulas or processed further to create concentrated extracts.
In conclusion, obtaining larval tears is a delicate process that involves raising silkworms, inducing pupation, and collecting the tears. This precious substance holds significant value in traditional Chinese medicine and has been used for centuries to treat various ailments. By following the steps outlined in this article, one can gain a better understanding of how to obtain and utilize this valuable ingredient.
