I bought MY no-needle Syringes from Amazon. I used them to add vegetable oil of 2mm into 5 gallons of Everclear whisky to cover the Sativa plant material I let soak for 4 weeks, stirring 3-4 times a day in 10 Gallon Steel Cooking Pot with cover. Used a small portable burner to boil the Everclear off and fan to blow fumes though screen on open door and outside door closed; but screen open on bottom when liquid got smaller for me to put in smaller cooker. I removed ALL material and screened it through wired hand strainer and paper towels. Saved material, still have it but it’s not useable now. From 5 gallons I ended up with only 1/2 oz of PURE liquid with some small pieces of material. Because there was still an alcohol ‘smell’ to it I placed the container in fridge, about a week later NO MORE alcohol smell. Then I used ONCE a day on top of piece of cake. My toes were going black with ridges and my doctor from 4 open heat valve replacements said I had diabetes Now I am cured.
