Guayacol is a chemical compound (It is derived from guaiacum officinale, a plant native to the Caribbean and Central and South America. It is a colorless to pale yellow liquid with a characteristic odor and is chemically known as 2-methoxyphenol) that has been used in some studies as an adjuvant to improve the effectiveness of local anesthetics in equine anesthesia. However, it is important to note that the use of guayacol as an adjuvant in equine anesthesia is still considered experimental and has not been widely studied or proven to be safe and effective.
Here are some potential pros and cons of adding guayacol to an equine anesthesia protocol:
- May improve the effectiveness of local anesthetics, potentially allowing for a lower dosage or reducing the need for additional anesthetics
- May have a beneficial effect on inflammation and tissue healing
- Lack of scientific evidence to support its use in equine anesthesia
- Potential for adverse effects, such as local irritation or allergic reactions
- May interact with other medications or anesthetics being used
There are a limited number of studies that have investigated the use of guayacol as an adjuvant in equine anesthesia. These studies have generally been small and have reported mixed results, with some finding that guayacol improved the effectiveness of local anesthetics while others did not observe any significant difference.
In humans, guayacol has been studied as a potential treatment for pain and inflammation associated with various conditions, such as osteoarthritis and wound healing. However, the results of these studies have been inconclusive and more research is needed to determine the effectiveness of guayacol in these indications.

In dogs, guayacol has been studied as an adjuvant to local anesthetics for use in dentistry and surgery. Some studies have found that the addition of guayacol to local anesthetics improved the effectiveness of the anesthetics, while others have not observed any significant difference.
In a study of dogs undergoing dental procedures, guayacol was administered at a dose of 0.1 mL/kg in combination with mepivacaine. In a study of horses undergoing surgical procedures, guayacol was administered at a dose of 0.2 mL/kg in combination with lidocaine.
