Palo Santo is generally considered safe for most people when used appropriately, but there are a few considerations regarding its potential toxicity: 

Smoke Inhalation 

While the smoke from burning Palo Santo is not inherently toxic, inhaling any type of smoke can irritate the respiratory system, especially for individuals with asthma, allergies, or other respiratory conditions. Prolonged exposure to smoke can cause coughing, shortness of breath, or discomfort. It’s important to use Palo Santo in a well-ventilated area to minimize smoke inhalation. 

Allergic Reactions 

Some individuals may be sensitive or allergic to the compounds in Palo Santo, particularly the essential oils. Symptoms of an allergic reaction might include skin irritation, itching, or respiratory symptoms like sneezing or a runny nose. If you experience any allergic reactions, it’s best to discontinue use and consult with a healthcare provider. 

Essential Oil Use 

Palo Santo essential oil, when used topically, should always be diluted with a carrier oil to prevent skin irritation. Applying undiluted essential oil directly to the skin can cause redness, itching, or burning. Additionally, essential oils should not be ingested unless under the guidance of a qualified healthcare professional, as they can be toxic if taken internally inappropriately. 

Pregnancy and Children 

Pregnant women and young children should use caution when using Palo Santo, especially in essential oil form. The effects of Palo Santo on pregnancy have not been well studied, so it’s advisable to consult a healthcare provider before using it during pregnancy. For children, always use Palo Santo in moderation and ensure the area is well-ventilated. 

Palo Santo is not toxic to humans when used correctly, but smoke inhalation, allergic reactions, and the improper use of essential oils can pose risks. It’s important to use Palo Santo mindfully and with awareness of any personal sensitivities.
