🔰 BADAM SHIRIN Vs BADAM TALKH — LET'S END THE BOTANICAL CONFUSION

A common question in Unani Medicine is:

Are Sweet Almond and Bitter Almond two different botanical species?

❗No.

According to the current Kew Plants of the World Online (POWO), the accepted botanical species is:

🌱 Prunus amygdalus Batsch
Family: Rosaceae

Both Sweet and Bitter Almond are placed under this same species.

🔬 BOTANICAL IDENTITY ≠ VARIETAL IDENTITY

Species-level identity:
Prunus amygdalus Batsch

Traditional Unani varietal/form distinction:
🔹 Badam Shirin (Sweet Almond) → P. amygdalus var. dulcis
🔹 Badam Talkh (Bitter Almond) → P. amygdalus var. amara

Kew currently treats both varietal names as synonyms under Prunus amygdalus.

❗THEN WHAT IS PRUNUS DULCIS?

This is the major source of confusion.

Prunus dulcis (Mill.) D.A.Webb is a widely used name for almond in scientific literature.

However, Kew currently treats Prunus dulcis as a synonym of Prunus amygdalus Batsch—not as a separate almond species.

Therefore, the simplest way to remember it is:

ONE ACCEPTED SPECIES:
🌱 Prunus amygdalus Batsch

TWO TRADITIONAL MEDICINAL FORMS:
🟢 Shirin → var. dulcis
🟤 Talkh → var. amara


🌿 WHY DOES THIS MATTER IN UNANI MEDICINE?

Although botanically they belong to the same species, Badam Shirin and Badam Talkh have different traditional medicinal identities and should not be casually substituted for one another.

Sweet Almond is readily available in the market.

Badam Talkh is comparatively less readily available and may be more costly, making authentic identification especially important.

So, when a Unani formulation specifically requires Badam Talkh, simply purchasing any product labelled “Badam” or “Kadwa Badam” is not sufficient.

🌿 THE APPLIED UNANI RULE

Botanical identity: Prunus amygdalus Batsch
↓
Traditional varietal/form identity: dulcis / amara
↓
Pharmacognostic authentication
↓
Correct medicinal use

And finally:

❌ Prunus amygdalus and Prunus dulcis are not two different almond species according to current Kew taxonomy.

❗Prunus amygdalus is the accepted species name, while Prunus dulcis is currently treated by Kew as a synonym.

In Applied Unani Medicine, knowing “Badam” is not enough. We must know exactly WHICH Badam—and authenticate it accordingly.
