While Palo Santo is generally considered safe and beneficial, there are a few potential side effects to be aware of, especially for individuals with specific sensitivities or conditions: 

Respiratory Irritation 

Palo Santo produces smoke when burned, and this smoke can be irritating to the respiratory system, particularly for individuals with asthma, allergies, or other respiratory conditions. Inhaling the smoke may cause coughing, shortness of breath, or other symptoms of respiratory discomfort. If you have a history of respiratory issues, it’s advisable to use Palo Santo in a well-ventilated area or consider using Palo Santo essential oil or sprays as an alternative. 

Allergic Reactions 

Although rare, some people may be allergic to Palo Santo. Symptoms of an allergic reaction might include skin irritation, itching, redness, or respiratory symptoms such as sneezing or a runny nose. If you experience any signs of an allergic reaction, discontinue use and consult with a healthcare professional. 

Headaches 

The strong aroma of Palo Santo, while generally pleasant, can be overwhelming for some individuals and may trigger headaches, particularly if used in a poorly ventilated area or in large amounts. If you are prone to scent-induced headaches, it may be best to use Palo Santo sparingly or in combination with other, less intense scents. 

Pregnancy Considerations 

Pregnant women should be cautious when using Palo Santo smudge sticks or incense, especially when burning the wood, as the smoke may cause nausea or respiratory discomfort. It’s advisable to consult with a healthcare provider before using Palo Santo during pregnancy and to consider using it in moderation or exploring non-burning alternatives like diffused essential oils. 

Environmental Concerns 

While not a direct side effect on health, it’s important to note that the overharvesting of Palo Santo has raised environmental concerns. Unsustainable harvesting practices can lead to the depletion of Palo Santo trees, affecting ecosystems and the communities that rely on them. It’s essential to source Palo Santo from ethical and sustainable suppliers to minimize environmental impact. 

While Palo Santo is safe for most people, it can cause respiratory irritation, allergic reactions, or headaches in some individuals. Pregnant women should use it with caution, and everyone should consider environmental impacts when sourcing Palo Santo.
