Camphor for Conjunctivitis: Does It Work?

Does Camphor (Karpura) help with conjunctivitis? In classical Ayurveda, yes, as an ingredient in eye preparations made by a practitioner. Of the substances linked to pink eye, camphor has one of the clearer classical records, but it is also one of the riskiest to use on your own.

The Bhavaprakash Nighantu calls camphor beneficial for the eyes (Chakshushya, Netrya) and lists eye diseases (Netra Roga) among its classical uses. It also lists relief of burning sensation (Dahaprashamana), a key complaint in an inflamed eye.

The Sushruta Samhita names camphor directly in its chapter on Pitta-type conjunctivitis.

A rasa-kriya (decoction concentrate) should be made with sugar and camphor, from palinda or madhuka (licorice).

Sushruta Samhita, Uttara Tantra, Chapter 10: Pittabhishyanda Pratishedha Adhyaya

Ayurveda calls conjunctivitis Abhishyanda, "that which overflows", and sees it mainly as aggravated Pitta, the hot dosha, in the eye. The Bhavaprakash Nighantu classes camphor as cold in potency (Sheeta Virya), which is why it fits a hot, burning eye. These are practitioner-made preparations. Never put camphor in your own eyes.

How Camphor Helps with Conjunctivitis

Ayurveda describes conjunctivitis as Pitta inflaming Alochaka Pitta, the part of Pitta that governs sight. The result is a red, burning, light-sensitive, weeping eye. The Sushruta Samhita gives the Pitta-type form (Pittabhishyanda) its own chapter, Uttara Tantra, Chapter 10, and camphor appears in it.

Cooling the burning

The Bhavaprakash Nighantu classes camphor as cold in potency and cooling (Sheetala), and says it relieves burning sensation. Burning is the signature symptom of the Pitta-type eye, so this is the most direct line of reasoning. The same text says camphor alleviates Pitta and Kapha.

A named eye action

Camphor also carries a specific eye action, beneficial for the eyes (Chakshushya), and the Bhavaprakash Nighantu calls it a key ingredient in many formulations for eye diseases. Its taste is bitter, pungent and slightly sweet (Tikta, Katu, Madhura).

Why it is always paired

Camphor is also sharp and penetrating (Tikshna), and some Ayurvedic sources warn that it can aggravate Pitta in excess. That is why the Sushruta preparations pair it with soothing partners, sugar and licorice, rather than using it alone. Our sources hold no modern research on camphor for conjunctivitis.

How to Use Camphor for Conjunctivitis

For conjunctivitis, camphor is a practitioner-only eye ingredient. Classical texts use it in prepared eye remedies, but our sources give no home recipe or eye dose, and camphor is harmful in excess.

Classical eye formulations containing camphorNot specified in our sourcesEye diseases, per the Bhavaprakash NighantuPractitioner-prepared
Household or worship camphorNoneNo roleUsually synthetic and toxic; keep away from the eyes and mouth

Choosing the right camphor matters

Our sources say only natural edible camphor (Bhimseni or Pakva Karpura) is suitable for any use near the face or inside the body. Even that grade stays away from the eye unless a practitioner is preparing a classical formula.

What the home approach looks like

The Ayurvedic home approach to conjunctivitis centres on cooling Pitta. Our condition sources describe a Triphala eye wash, rose water to soothe and ghee to calm the heat within. Ask a practitioner how to prepare these safely.

Safety first

See an eye doctor for any red, painful or discharging eye. Do not self-apply camphor, or any oil, paste or powder, to the eye. Avoid camphor in pregnancy, with a seizure history, and around young children.

Frequently Asked Questions

Can I put camphor in my eye for pink eye?

No. Classical eye preparations with camphor are made and applied by practitioners. Worship camphor is usually synthetic and toxic, and our sources warn that camphor is harmful in excess. See an eye doctor for a red, painful or discharging eye.

Which classical texts link camphor to conjunctivitis?

The Sushruta Samhita, Uttara Tantra, Chapter 10, uses camphor with sugar and licorice in preparations for Pitta-type conjunctivitis. The Bhavaprakash Nighantu lists eye diseases among its uses and calls it beneficial for the eyes.

Is camphor cooling or heating?

The Bhavaprakash Nighantu classes it as cold in potency and cooling. It is also sharp and penetrating, and some Ayurvedic sources say it can aggravate Pitta in excess. That is why it is used in small amounts with soothing partners.

What are gentler alternatives?

Licorice is camphor's partner in the Sushruta preparation, Palash appears in the same chapter, and Rose is a soothing Pitta-cooling option.

Safety & Precautions

Camphor is not a herb to take casually. Our sources agree that it works in small amounts and turns harmful in larger ones, so the honest summary is this: external and aromatic use in sensible amounts, internal use only under a qualified practitioner.

Overdose and toxicity

Ayurvedic practice warns that camphor should only be used in prescribed low doses, because excessive use acts as a narcotic poison. Our editorial sources add that camphor is neurotoxic in excess and can lower the seizure threshold, with nausea, vomiting and confusion as early signs and seizures at higher doses.

The Bhavaprakash adds a quieter warning: excessive use can reduce sexual potency.

Synthetic camphor

The camphor sold for worship is usually synthetic and is toxic if swallowed. Never use it in the mouth, eyes or any internal preparation. Only natural edible Bhimseni or Pakva Karpura is suitable for any use near the face or inside the body.

Who should avoid it

  • Infants and young children: keep camphor well out of reach and do not apply it to their face or chest. Small amounts swallowed can be dangerous.
  • Pregnancy: our sources advise avoiding it.
  • Seizure history or epilepsy medication: avoid, because camphor can lower the seizure threshold.
  • Asthma: strong vapour can trigger bronchospasm, so inhale cautiously or not at all.
  • G6PD deficiency: our editorial sources list it as a contraindication.

Skin and eyes

Do not apply neat camphor to inflamed skin, and avoid broken, weeping or freshly scratched skin, where it stings and can worsen the wound. Keep it away from the eyes unless a practitioner is preparing a classical eye formula.

Pitta caution

Although the Bhavaprakash classes camphor as cooling, other Ayurvedic sources describe it as slightly heating and warn that it can aggravate Pitta in excess. Its sharp quality can also irritate already sensitive tissue. If you run hot or your tissues are inflamed, use less, not more.

Our sources do not record specific drug interactions beyond anti-epileptic medication. If you take any regular medication, talk to your doctor before using camphor.
