Sage Leaves Side Effects

Sage leaves are generally safe for most people when used in moderate culinary amounts. However, when used in larger quantities or in medicinal preparations, sage can have some potential side effects and interactions to be aware of. Here are some possible sage leaf side effects and considerations:

Allergic Reactions

Some individuals may be allergic to sage and may experience allergic reactions, including skin rashes, itching, and swelling. If you suspect an allergy to sage, discontinue use and seek medical attention if symptoms are severe.

Gastrointestinal Distress

Consuming large quantities of sage leaves or sage supplements can lead to digestive upset, including stomach pain, diarrhea, and nausea. It’s best to use sage in culinary amounts or as directed by a healthcare professional.

Drug Interactions

Sage may interact with certain medications, including blood thinners and anticonvulsants. If you are taking any prescription medications, consult your healthcare provider before using sage supplements or consuming sage in medicinal amounts.

It’s important to note that most people can enjoy sage as a culinary herb without experiencing any adverse effects. However, if you are considering using sage in medicinal amounts or as a supplement for specific health purposes, it’s wise to consult with a healthcare professional, particularly if you have any underlying medical conditions or are taking medications.
