What are the health risks of shiso?

Shiso is generally safe for most people when consumed in moderate amounts as a food ingredient. However, there are a few potential health risks associated with shiso:

1. Allergic Reactions: Some individuals may be allergic to shiso, particularly those who are allergic to other plants in the mint family, such as basil, mint, or oregano. Allergic reactions to shiso can range from mild itching and hives to more severe symptoms such as difficulty breathing or anaphylaxis.
2. Oxalate Content: Shiso contains oxalates, which are naturally occurring compounds found in many plants. Consuming foods high in oxalates can contribute to the formation of kidney stones in susceptible individuals. People with a history of kidney stones may need to moderate their intake of high-oxalate foods like shiso.
3. Interactions with Medications: Shiso contains compounds that may interact with certain medications. For example, shiso oil may slow blood clotting, so it should be used with caution in individuals taking blood-thinning medications. It’s important to consult with a healthcare provider before using shiso supplements or extracts if you are taking any medications.
4. Potential Contamination: Like other fresh produce, shiso can be contaminated with bacteria such as E. coli or Salmonella, especially if not handled or washed properly. It’s important to wash shiso thoroughly and store it properly to reduce the risk of foodborne illness.

Overall, shiso is a nutritious herb that can be a healthy addition to your diet. It’s important to consume it in moderation and be aware of these potential risks, especially if you have certain health conditions or are taking medication. If you have concerns about consuming shiso, consult with a healthcare professional.
