Generally speaking, shepherd's purse contains oxalic acid. The detailed analysis is as follows:

Shepherd's purse leaves and stems contain a certain amount of oxalic acid. Oxalic acid is a natural product of plant metabolism and is relatively abundant, particularly in fresh shepherd's purse. If large quantities of untreated shepherd's purse are consumed directly, such as in cold dishes or through quick stir-frying, oxalic acid may combine with calcium in the body to form calcium oxalate, which could potentially have adverse effects on individuals at high risk for kidney stones or those with weak digestive systems.

Before consuming shepherd's purse, it should be thoroughly washed, then blanched in boiling water and subsequently rinsed clean with cold water. Blanching removes most of the oxalic acid, reducing its impact on calcium absorption. Additionally, this process enhances the tenderness and flavor of shepherd's purse by reducing bitterness. However, blanching cannot completely eliminate all oxalic acid. Therefore, it is important to control the portion size and avoid consuming large quantities at one time.

In daily diets, it is recommended to appropriately combine different foods and manage portion sizes to avoid excessive consumption of any single food item, which contributes to maintaining good health.
