Yes. The Rhino Rescue Project horn treatment methodology is the only legally recognised treatment option available at present (a full legal opinion is available upon request). 

Treatment compounds are infused into the horn using a system through which a high-pressure device forces liquids into the tubular structure of the horn (patent pending). The system was designed by RRP’s wildlife veterinarian, Dr. Charles van Niekerk, and is also the only poaching intervention currently endorsed by the insurance industry.
