The heat of peppers is measured using the Scoville Heat Scale, which ranks the heat of a given pepper in units known as Scoville Heat Units (SHU). Bell peppers of all colors register zero SHU, meaning they're not hot at all. Jalapeños are medium, measuring 2,500 to 8,000 SHU, while extremely hot chiles like habaneros or Scotch bonnets come in at 100,000 to 350,000 SHU.

This is why sriracha is more of a chili paste than a sauce with its thick consistency. It has fewer notes of other flavors since it has fewer ingredients than hot sauces but it’s also why the spicy hot taste is more straightforward than hot sauces. This is also why the chill used is so important.

Curcumin dietary supplements containing curcumin root extract are another form of curcumin intake. Supplement labels will indicate different percentages of curcumin extract. Independent quality control and quality assurance laboratories test and inspect the product to verify these claims and endorse the label as directed by the manufacturer of the product. Some curcumin dietary supplement formulations may also contain other extracts, such as black pepper extract (piperine) or proprietary mixtures containing vegetable gums, or other lipid preparations, in an attempt to improve the bioavailability of curcumin. In particular, research has shown that curcumin can be used as a topical agent in formulations of collagen films, lotions, sponges and bandages to promote healthy skin.
