Claims

OCR 09WP 14 / 05 / 2569 1. A gel patch formula containing cannabis leaf extract for pain relief, which includes: Agar powder, quantity 0.5 - 4.0 percent by weight. Clean water, 20.0 - 80.0 percent by weight. Cannabis leaf extract concentration: 19.1 - 76.4 percent by weight.

2. Manufacturing process of cannabis leaf extract gel patches for pain relief, based on the following formula: Claim 1, which involves the following steps: Preparation of cannabis leaf extract. A. Wash the fresh cannabis leaves thoroughly and let them dry. B. Take the fresh cannabis leaves from step A, chop them finely, and soak them in 40-degree white liquor in the following ratio: Mix cannabis leaves with 40-degree white liquor at a ratio of 1:10 (kilograms per liter) in an opaque glass container. Seal tightly and let it steep. 15 days C. Next, filter the mixture from step B to separate the cannabis leaf residue from the 40-degree white liquor. Cover the cannabis leaf extract with cheesecloth and store it at room temperature in an opaque glass container. Let it settle. For a period of 1 day. d. Next, separate the clear portion from the sediment. The clear portion obtained is the cannabis leaf extract. Production of agar patches containing cannabis leaf extract.

4. Mix the agar powder into clean water, then heat it to a temperature of 95-100 degrees Celsius. For 3-5 minutes, until a clear solution is obtained. F. Take the agar solution from step E and let it stand at room temperature until its temperature cools down to... 50 - 60 degrees Celsius B. Mix the cannabis leaf extract from step D with the agar solution from step F, pouring it in slowly. Along with the stirring, mix the solution until it is homogeneous. C. Pour the resulting mixture into the mold and let it sit at room temperature for 15-30 minutes. To induce solidification and form into a sheet, a gel patch containing cannabis leaf extract was created for relief. For pain relief, store at a temperature of 2-4 degrees Celsius.
