Side Effects Of Camphor

1. Lip Dryness

Camphor may cause the lips to over dry. It is otherwise used to treat various skin inflammations, but it can lead to acute lip dryness as well. The lip skin starts peeling and flaking. It needs medical guidance to treat lip dryness caused as an allergic reaction to camphor (1).

2. Rashes

Camphor leads to skin redness and rashes when over-used. Red rashes develop all over the skin. Those rashes can be painful and itchy at times. It can be exceptionally tough to deal with the itching and pain caused due to such rashes at home (1).

3. Eczema

Eczema is another skin condition that can be a result of camphor side effects (2). Eczema is marked by excessive skin drying, swelling of the eye region and other soft facial tissues, pain, irritation, and flaking (1), (3). This is a severe skin condition that cannot be treated at home. It needs immediate medical attention for instantaneous and long-term relief. The one thing that you need to know is that camphor is not edible. It is strictly meant for external application. Thus, it is highly dangerous to apply camphor on broken and peeled skin. It is extremely toxic if ingested by any direct or indirect means.

4. Toxicity

Camphor is highly toxic for humans. Its small amounts too can lead to death in children and toxicity in adults (4). Camphor hepatotoxicity is a serious side-effect of camphor ingestion. It leads to liver (hepatic) damage and sudden death (5), (6).

Also, steer clear of yellow and brown camphor oil even in topical applications. Their high safrole content makes them carcinogenic and toxic.

5. Seizures

Camphor can cause acute chemical imbalance in the brain. This leads to seizures (4). This is a very serious side effect of camphor ingestion (1), (4), (5). This is the reason that you should be careful of using camphor in any form if you have epilepsy.

6. Respiratory Problems

Camphor can also cause respiration upset. This is an acute medical condition for children and infants suffering from respiratory disorders. Avoid the use of camphor completely on children who suffer from bronchitis or asthma. Camphor is highly dangerous for such children, as it causes chest congestion and sudden respiratory arrest (5).

7. Pregnant And Lactating Mothers

Camphor is highly dangerous for lactating mothers and pregnant ladies. It gets absorbed by the placenta and can cause neurological and physical damage to the fetus (7). It can easily get absorbed through skin cracks and reach for milk in lactating mothers. It leads to camphor hepatotoxicity in children and infants as already mentioned (5).

8. Parkinson’s Disease

Camphor is believed to be dangerous for people suffering from Parkinson’s disease. It may interfere with the medicine used in Parkinson’s and increases the toxicity level. It may turn out to be very poisonous in such cases. Though there are not enough studies to prove this claim, it is best to be careful as camphor toxicity may cause seizures and neurological issues (8).

9. Scalp Issues

The application of camphor in the form of camphor oil is considered an amazing therapeutic therapy. However, it holds a prevalent danger too. Applying camphor on itchy, broken, and peeling scalp/skin is extremely risky. It can easily get absorbed through cracks on the scalp. This is one of the most dangerous camphor oil side effects that leads to further itching of scalp and skin, and camphor poisoning (9).

10. Chest Problems

Camphor can lead to discomfort or burning in the chest (10). It induces a feeling of tightness and fullness in and around the chest region. It may also lead to swelling of the affected area.

Camphor has conventionally been called a healing herb. But people have stayed ignorant of the severe side effects of camphor. It has as many side-effects as its uses. You may consider using camphor in small amounts, but its larger doses are fatal.
