If you’re looking to make that sound more natural or grammatically correct, here’s a polished version:
This remedy is said to help remove kidney stones, dissolve small stone fragments (“gravel”), and relieve urinary tract infections. I’ll explain the recipe in detail, along with how to prepare it and use it properly.
If you’re describing a traditional or herbal remedy, it’s a good idea to phrase the claims as “is said to help” unless they have strong clinical evidence. I can also make it sound more conversational, promotional, or suitable for social media if you’d like.
