Sandalwood (Chandan): what it cools and soothes

Sandalwood is the most adulterated substance most people ever put on their skin. Genuine Santalum album is scarce and costly, so the pale paste sold as chandan is frequently scented polymer, and the cooling you feel is often the perfume rather than the wood.

What the word covers

• Santalum album, Indian sandalwood, is the real one. It is a slow-growing tree, protected, and its legal supply is genuinely limited.
• Australian sandalwood, Santalum spicatum, is a different oil from a related tree. It is legitimate, cheaper, and does not behave identically.
• Chandan powder and sticks at the market are often another wood dyed and soaked in fragrance. Small shops sell blocks of it that float oddly and burn black.
• Commercial chandan-flavoured drinks and soaps use synthetic sandal fragrance. Nothing in them is wood.
• The oil, not the paste, is where the actual chemistry sits — and the oil is what you must never drink.

What it is used for

• Prickly heat, sun-warmed skin and the itchy red of a Delhi summer, as a cool paste on intact skin.
• A thin layer on the forehead at night for the heavy, hot-headed feeling that comes with heat and no sleep.
• Traditional use for burning urination, where the herb is given as part of a formulation and not as a spoon of powder in water.
• Perfume and incense, which is honest use and does not need a health claim attached.
• In small studies, inhaled sandalwood aroma reduced subjective calm-state anxiety. That is a fragrance finding, not a medicine.

Where the claim outruns the fact

• It does not lower a real fever. A child at 102 with a chandan paste on the forehead is a child whose fever is being decorated, not measured.
• It does not treat acne, and on an oily face a paste base is a way to add more blocked pores.
• It does not close a wound. Never on broken, blistered or weeping skin.
• It is not a sunburn treatment on a blistering burn.
• The cooling is largely a sensory effect. Pleasant, harmless on good skin, and not an anti-inflammatory you can dose.

What goes wrong

• Allergic contact dermatitis from the paste, showing as a red itchy rectangle exactly where it was applied. Synthetic sandalwood fragrance is a well-known sensitisser, and that is the usual culprit.
• A darkening, rough patch where a gritty paste was rubbed daily.
• Drinking sandalwood oil or a concentrated preparation: nausea, vomiting, and real kidney irritation. This is a genuine emergency, not a rough evening.
• Incense smoke in a closed room in someone with asthma or a cough that will not leave.

How it is used sensibly

• Paste on intact skin only, thin, off after it dries, with water and no scrubbing.
• Rose water or plain cool water as the base. Milk makes it heavier and feeds bacteria on skin that is already breaking out.
• A patch test on the inner forearm for a day before the first face application, especially if the source is a loose powder from a general shop.
• Oil for fragrance and massage diluted, never undiluted on the face, never by mouth.

What we ask before it is part of a plan

• Where the paste came from, because the answer decides whether it is a herb or a fragrance.
• Whether the skin problem is heat rash, eczema, fungal, or contact allergy to something already being applied.
• Whether the complaint being treated is actually a fever, and if so what the temperature has been and for how many days.
• Burning urination needs a urine test before it needs any herb, because the two common causes go in opposite directions.

Aksa physicians have been consulting on Ayurvedic care since 1992. In a free video consultation they will tell you whether chandan belongs in your routine at all, what quality is worth buying, and where a cooling paste stops being enough.
