What is White Silk Cotton?
If you have ever come across kapok fibre, you have met this tree already. The White Silk Cotton Tree gives that fibre from its seed pods, and Ayurveda also uses its gum, root and bark as medicine.
White Silk Cotton (Kutashalmali), also called the True Kapok Tree, is botanically Ceiba pentandra (Linn.) Gaertn. It is the white-flowered variety of Silk Cotton (Shalmali), and it grows widely in the Southern and Western parts of India. Other Sanskrit names include Shvetashalmali (white Shalmali), and in Hindi it is Safed Semal.
The Bhavaprakash Nighantu, a classical Ayurvedic materia medica, describes it in Varga 5, verse 30. It says its medicinal properties are similar to the red Shalmali, though it is considered slightly less potent.
Benefits of White Silk Cotton
The Bhavaprakash Nighantu records three therapeutic actions for White Silk Cotton, each tied to a specific part of the tree.
Reproductive Vitality
Its gum and root are used as aphrodisiacs (Vrishya). This fits its profile: a sweet (Madhura) taste and sweet post-digestive effect (Vipaka), with heavy (Guru) and unctuous (Snigdha) qualities, the kind Ayurveda associates with building and nourishing.
Digestion and Loose Stools
The bark is used in dysentery. Its listed binding action (Stambhana), meaning it helps hold back excessive discharge, is supported by its astringent (Kashaya) taste. Tannins appear among its recorded constituents.
Nourishment
It is also classed as nutritive (Pushtikara), consistent with its sweet, heavy and unctuous nature and its cold potency (Sheeta Virya).
Its medicinal properties are similar to the red Shalmali but it is considered slightly less potent.Bhavaprakash Nighantu, Varga 5, verse 30
How to Use White Silk Cotton
The Bhavaprakash Nighantu gives its dose simply as "similar to Shalmali" and does not set out a separate figure. The part you use depends on the goal.
| Form | Dose | Best For | When to Take |
|---|---|---|---|
| Gum | Similar to Shalmali | Aphrodisiac use (Vrishya) | As directed by a practitioner |
| Root | Similar to Shalmali | Aphrodisiac use | As directed by a practitioner |
| Bark | Similar to Shalmali | Dysentery | As directed by a practitioner |
Our sources record no specific vehicle (anupana) or seasonal guidance for it.
Safety & Side Effects
Our sources record no specific contraindications, drug interactions or overdose signs for White Silk Cotton. What they do record helps you think about who should be careful.
- Binding action: it is classed as binding (Stambhana), so it is not a sensible choice if you are prone to constipation.
- Heavy and cooling: its heavy (Guru), unctuous (Snigdha) qualities and cold potency (Sheeta Virya) mean a practitioner should judge whether it suits your digestion.
- Dysentery: dysentery needs medical assessment; do not treat it with herbs alone.
- Pregnancy, nursing and medication: no data is recorded, so speak with your doctor first.

White Silk Cotton is mainly a practitioner's herb, and its dose is given only by reference to the red Silk Cotton (Shalmali). The simplest starting point is to look for products made from Silk Cotton (Semal) and ask a qualified Ayurvedic practitioner whether the white or red variety suits your goal.

| Comparison | White Silk Cotton | Alternative | Verdict |

| White Silk Cotton vs Red Silk Cotton (Shalmali) | White-flowered; similar properties, slightly less potent | The red variety it is measured against | Choose the red variety when you want the stronger effect; the white is a milder alternative |
| Gum and root vs bark | Gum and root used as aphrodisiacs | Bark used in dysentery | Pick the part that matches the goal |
| Kapok fibre vs medicinal parts | Fibre from the seed pods | Gum, root and bark | The fibre is a material, not a medicine; only the gum, root and bark have recorded uses |
