Coumarin is a chemical compound that was originally derived from the tonka bean. It has been used in perfumes and food flavoring since 1882, but it can also be found naturally occurring in some plants like sweet clover (Melilotus officinalis) or dittany of Crete (Origanum dictamnus). The coumarins are commonly referred to as “coumadin” which is actually just one specific type of these compounds.

Coumarin: Frequently asked questions

What types of Coumarin are there and what determines a good product?

Coumarin is a naturally occurring chemical found in many plants. It can be extracted from the tonka bean, sweet clover and other plant sources. The most common form of coumarin used as a food additive is called d-coumaric acid or dl-3-(4′-hydroxyphenyl)-propionic acid (CAS# 513-86-0). This type of coumarin has been shown to cause liver damage at high doses in laboratory animals; however, it does not appear to pose any risk for humans when consumed at levels typically found in foods . Another type of coumarin that occurs naturally is known as 4′,5′-dihydroxybergamottin (also referred to simply as bergapten), which may have some cancer prevention properties but also causes skin irritation . Bergapten was first isolated from grapefruit juice by researchers who noticed an unusual bitter taste associated with consuming this fruit.

The quality of the Coumarin is determined by its purity, and how much it costs. A purer product will cost more than a less pure one.

Who should use a Coumarin?

Anyone who wants to avoid the side effects of synthetic drugs.

Based on what criteria should you buy a Coumarin?

The most important factor is how it sounds to you. If the Coumarin has a sound that appeals to you, then buy it. It doesn’t matter if other people think your choice of instrument is “wrong”. You should play what makes YOU happy and not worry about whether or not others will like what they hear.

Make sure you compare the milligrams of Coumarin in each product.

What are the advantages and disadvantages of a Coumarin?


The advantages of a Coumarin are that it is very easy to use and has many features. It can be used by the beginner as well as the professional, because it offers great flexibility in its usage.


The main disadvantage of a Coumarin is that it can be dangerous to your health. It has been linked with liver damage and even death in some cases, so you should not use this drug if you have any pre-existing medical conditions or are taking other medications which could interact negatively with the Coumarin.
