What are the side effects of mastic gum? A comprehensive guide for informed use.

5 min read

While the FDA has classified mastic gum as generally recognized as safe (GRAS), it is only considered safe for use for up to three months, as its long-term effects have not been extensively studied. Understanding what are the side effects of mastic gum is crucial for anyone considering this popular health supplement.

Quick Summary

Examine the potential drawbacks of using mastic gum, from mild gastrointestinal issues to risks of jaw problems and allergic reactions. Learn about safety precautions for vulnerable groups and how to use it responsibly.

Key Points

  • Mild Gastrointestinal Upset: Initial use of mastic gum can cause mild, temporary symptoms like nausea, bloating, and diarrhea as the body adapts.

  • Risk of Jaw Strain: Excessive or intense chewing of hard mastic gum can lead to soreness and potentially aggravate or contribute to temporomandibular joint (TMJ) disorders.

  • Allergic Reaction Potential: Individuals with allergies to other Pistacia species or tree resins may be susceptible to allergic reactions from mastic gum.

  • Not Recommended for Certain Groups: Pregnant or breastfeeding women and children should avoid mastic gum due to a lack of safety research.

  • Interactions with Medications: There are some warnings about possible interactions with certain drugs, such as blood thinners and antibiotics, necessitating a doctor's consultation.

  • Damage to Dental Work: The hard and sticky nature of mastic gum may dislodge or damage existing dental fillings or crowns.

What is Mastic Gum?

Mastic gum is a resin derived from the Pistacia lentiscus tree, native to the Mediterranean region, particularly the Greek island of Chios. This resin, often called the “tears of Chios” for its droplet-like shape, has been used for centuries in traditional medicine and culinary applications. It is known for its purported benefits, including supporting digestive health, possessing antimicrobial properties, and aiding oral hygiene. However, as with any supplement, it is not without potential risks, and understanding these is key to safe usage.

Common Side Effects of Mastic Gum

In clinical trials, mastic gum has generally been well-tolerated, with side effects typically being mild and temporary. These symptoms often occur as the body adjusts to the supplement, especially when first introduced.

Gastrointestinal Discomfort: Some individuals may experience mild digestive issues, such as nausea, bloating, diarrhea, or constipation. These issues are often transient and can sometimes be managed by adjusting the dosage or taking the supplement with food. The bioactive compounds in the resin, including polyphenols and triterpenes, can influence digestive enzymes and gut microbes, which may lead to temporary upset.

Headache and Dizziness: Less commonly, some users have reported experiencing headaches or a feeling of dizziness. If these symptoms occur, it may be a sign to reduce the dose or discontinue use, and a healthcare provider should be consulted if they persist.

Risks Associated with Excessive Use

The natural toughness of mastic gum, which provides resistance training for jaw muscles, also poses potential risks when chewed excessively or incorrectly.

Temporomandibular Joint (TMJ) Strain: Due to its hardness, chewing mastic gum requires more effort than regular gum. Overworking the jaw muscles through frequent or prolonged chewing can lead to muscle fatigue, soreness, and, in some cases, the development or worsening of TMJ disorders. Symptoms can include pain, clicking, or grinding sounds in the jaw joint.

Damage to Dental Work: Individuals with extensive dental work, such as fillings, crowns, or veneers, should exercise caution. The tough, sticky nature of mastic gum has the potential to stress or dislodge dental restorations, especially if they are weak or old. Starting with smaller, softer pieces and consulting a dentist is a prudent step for those with concerns.

Potential for Allergic Reactions: As mastic is a natural tree resin, there is a risk of allergic reaction, particularly for those with sensitivities to the flowering plant Schinus terebinthifolius or other species in the Pistacia family (which includes pistachios and cashews). Allergic reactions may manifest as rashes, hives, or swelling and require immediate medical attention.

Special Precautions for Vulnerable Groups

There is a general lack of scientific research on the safety of mastic gum for certain populations, leading to specific recommendations for avoidance.

  • Pregnancy and Breastfeeding: Due to insufficient reliable safety information, women who are pregnant or breastfeeding are advised to avoid using mastic gum.
  • Children: For similar reasons of limited research, and the potential choking hazard from the small, hard pieces, children should not consume mastic gum, especially in its natural resin form.

Potential Drug Interactions

While interactions are not well-documented, some anecdotal reports and warnings suggest potential conflicts with certain medications.

  • Blood Thinners: Mastic gum may potentially interfere with anticoagulant medications, so those on blood thinners should consult a doctor before use.
  • Antibiotics: Some evidence suggests potential issues when taking mastic gum in conjunction with certain antibiotics, particularly for H. pylori eradication.
  • Antacids: The effects of mastic gum on stomach acid production could potentially interact with antacid medications.

Always discuss with a healthcare provider before combining mastic gum with any medication.

Comparison: Mild Side Effects vs. Risks of Excessive Use

To put the potential downsides into perspective, here is a comparison of typical mild side effects versus the more significant risks of overuse.

Feature Mild Side Effects Risks of Excessive Use
Cause Initial bodily adjustment to compounds in the resin. Repetitive strain on jaw muscles and potential for stress on dental work.
Symptoms Nausea, diarrhea, constipation, mild headache, or dizziness. Jaw soreness, fatigue, pain, clicking/popping in the TMJ, potential damage to fillings.
Frequency Can occur when starting or increasing dosage. More likely with long-term, frequent, or vigorous chewing habits.
Duration Often temporary, subsiding as the body adjusts. Can become persistent or chronic if habits are not changed.
Management Lower dosage, take with food, or temporary discontinuation. Reduce chewing time and intensity, alternate chewing sides, seek professional dental advice.

How to Minimize Risk and Chew Mastic Gum Safely

To reap the potential benefits while minimizing the risk of adverse effects, consider these tips:

  • Start Small: Begin with a small amount of mastic gum, chewing for just 15-20 minutes a day to allow your jaw muscles to adjust.
  • Increase Gradually: Slowly increase the chewing duration and frequency over time if your body tolerates it well.
  • Alternate Chewing Sides: To prevent uneven muscle development and jaw strain, make sure to chew evenly on both sides of your mouth.
  • Listen to Your Body: Pay close attention to any signs of jaw pain, fatigue, or discomfort. If symptoms appear, reduce chewing time or stop entirely.
  • Consult a Dentist: If you have extensive dental work or a history of TMJ issues, speak with a dentist before starting a mastic gum regimen.
  • Choose Reputable Brands: As supplements are not strictly regulated, opt for high-quality, reputable sources to ensure purity and avoid contaminants.

Conclusion

While generally well-tolerated and recognized for its various health benefits, mastic gum does carry potential side effects and risks that users should be aware of. The most common issues are mild, temporary gastrointestinal upset and jaw soreness from excessive chewing. However, more serious risks, such as TMJ problems, damage to dental work, and allergic reactions, can occur, especially with overuse. Special care should be taken by pregnant or breastfeeding women, children, and individuals with certain tree allergies or those taking specific medications. By starting with a low dose, practicing moderation, and consulting with a healthcare professional, individuals can enjoy the potential therapeutic effects of mastic gum while mitigating its possible drawbacks.
