The sap is white but quickly turns brown on exposure to the air. I too have used it for many years to treat minor skin cancers and sun spots and know it to be safe and effective.
Milk Thistle
★★★★★
I never went to the doctor again for BCCs and I have treated dozens of them over the last 30 years or so using the Milk Thistle. You simply break the stem near the top where it is soft, wait a few seconds for the white sap to rise, and dab it on. Then leave it. After an hour or so it will turn a brown colour and after a few days will turn almost black. It sticks like tar and will not come off, even in the shower, providing you dont scrub it! After a week or so it will gradually wear off and the BCC will be much reduced if not gone altogether. Persistent cases may need a second application. It is painless, does not leave a scar or loss of pigment; it is simple to use and it's free! The whole world should know about the old fashioned "cow-cocky" remedy, but I guess that would put a lot of fancy skin cancer clinics out of business.
