Can I scrape my back with linseed oil?

Hello, yes. Scraping itself is highly irritating. Considering the personal skin's acceptance of scraping, if you choose irritating lubricating oil, it may cause pain in the scraping area, so the requirements for lubricating oil are generally non-irritating, such as BB oil and edible oil. Under special circumstances, lubricating oil with less irritation, such as Wanhua oil, can be used.
