  2. Allergic Reactions: Some people might be allergic to parsley and can experience skin reactions or more severe allergic responses.
  3. Drug Interactions: As a natural diuretic, parsley might interact with certain medications, especially diuretics and anticoagulant/antiplatelet drugs.
  4. Pregnancy Concerns: Excessive consumption of parsley, especially its oil and seeds, might lead to uterine contractions and should be avoided by pregnant women.
  5. Excessive Vitamin K: While vitamin K is beneficial for blood clotting, very high levels can interfere with certain medications, like warfarin, and potentially increase the risk of clotting too quickly.
  6. Photosensitivity: In very rare cases, direct skin contact with parsley followed by exposure to sunlight might lead to skin inflammation or photosensitivity in some individuals.

As with any herb or supplement, it's essential to consult with a healthcare provider before making significant changes to one's diet or before using parsley for therapeutic purposes.
