First of all, to clarify, there is no such thing as ginger foot patch in old Beijing. The main ingredients are bamboo vinegar powder and core Chinese medicine powder.

1. Among the foot patches, old Beijing is the best one, and ginger Artemisia is the most common one, which belongs to the general foot patch.

2. The cost of bamboo vinegar is the highest, and wormwood is the lowest, so the effect is average. Other auxiliary materials are added mainly to reduce the cost.

3. Most of the foot stickers are made in the market, processed in the factory, and the formula is uniform. It seems that the brand packaging is different. In fact, the raw material formula is the same, basically the same. It's just that old Beijing has adopted a unique core formula, which is different from the open formula, and the cost and effect are very different. So you need to know this standard when you choose.
