Sunny Isle sells two Jamaican black castor oils, Original and Extra Dark, and the brand says both are made from castor beans roasted, hand ground and boiled. Its label claims are about process and ash content, and the brand publishes no test results for either. This is what the brand’s own store states, and where that stops.
What does Sunny Isle say about how the oil is made?
The brand’s About Us page says the beans are roasted and ground by a manual grinder, then boiled to extract the oil. It adds that Sunny Isle roasts longer than other brands, which it credits for the dark brown color and a higher ash content.
That matches the traditional method we describe in what roasting changes in black castor oil.
The claim that this makes it more effective than any other castor oil is the brand’s own. No comparison data sits behind it on the pages I read.

At the 8 oz size that works out to about $1.75 an ounce for Original and $2.00 for Extra Dark. Both pages list no added salt.
Neither page gives an ash percentage, so you cannot compare the two on a number.
What should you check before you buy?
First, the origin wording is mixed. The About Us page says the products are made in the USA using globally sourced components, while another section says the seeds are grown and processed by farmers in rural Jamaica. Both statements are on the same page.
Second, the product text calls the oil organic but names no certifier in the text I read.
Third, a dark, thick oil is a feel and texture choice. For what to expect on your scalp, read black castor oil for hair growth, and for the regular-versus-roasted question see Jamaican black castor oil vs regular castor oil.
My pick, if you want to try it: the 4 oz Original. It is the cheapest way to learn whether you like a medium oil before paying more for the thicker one.
