Can the traditional Chinese medicine capsules developed by our family be sold without applying for patents? My family runs a clinic and has a small sprayer. )

Well, if your pharmaceutical ingredients are not independently studied by others, you apply for a patent first, then you are not infringing. Whether you have applied for a patent or not has little to do with selling products. I don't know what qualifications are needed to sell medicine. You can ask the drug administration. If the effect is good, I suggest you apply for a patent to protect the product.
