Shallaki (Boswellia): benefits, side effects and how to take it

By the Skeptics editorial team · Last reviewed 10 October 2026 · How we grade evidence

In short

Shallaki is the Ayurvedic name for the gum resin of Boswellia serrata, also called Indian frankincense. Trials in people with knee joint problems report less pain and stiffness after at least four weeks of use. Most of those trials are small and use specific enriched extracts, so results do not automatically apply to every product.

Questions people ask

Straight
answers.

Taken from real searches in India.

Is shallaki the same as boswellia?

Yes. Shallaki is the Sanskrit name for Boswellia serrata. Salai guggal and Indian frankincense are other names for the same resin.

Is shallaki the same as guggul or gond katira?

No. Guggul is the resin of a different tree, Commiphora wightii. Gond katira is an edible gum from other plants. Neither is shallaki.

Is shallaki good for knee pain and joint pain?

This is its best-studied use. A 2020 analysis of seven trials with 545 people found that Boswellia extract reduced pain and stiffness and improved joint function in knee osteoarthritis. The trials were small and used different extracts.

How long does shallaki take to work?

The same analysis suggested at least four weeks of continuous use. It is not a fast-acting painkiller.

Is shallaki a painkiller?

Not in the usual sense. It does not act like paracetamol or ibuprofen. In trials, pain scores fell gradually over weeks.

Is shallaki good for rheumatoid arthritis, sciatica or spondylosis?

There is not enough human evidence to say. Most trials are in knee osteoarthritis. These conditions need a doctor's care.

How much shallaki per day?

Trials used very different amounts, from about 100 to 250 mg a day of AKBA-enriched extracts up to around 1 g a day of standard extract. Because products differ so much, follow the label.

What is the best time to take shallaki?

No trial has compared timings. With food is the usual advice, to reduce stomach upset.

Can I take shallaki daily?

Trials gave it daily for periods of four weeks to several months. Long-term safety data is limited.

What are the side effects of shallaki?

Stomach upset, nausea, acidity and loose stools are the most reported. Skin rash is uncommon.

Is shallaki a blood thinner?

There are a few reports suggesting Boswellia may interact with blood-thinning medicine. The evidence is limited, but anyone on such medicine should ask a doctor first.

What is AKBA?

AKBA is one of the boswellic acids in the resin and the one most studied. It makes up only a small percentage of natural resin, and many labels do not state it at all.

Shallaki vs hadjod: which is better?

They are different plants studied for different things. Hadjod is Cissus quadrangularis and is traditionally used for bones. Shallaki is studied for joint comfort.

Why does one label say 65% boswellic acids and another much less?

Often because of the test. Titration counts every organic acid in the resin, while HPLC measures the boswellic acids individually and gives a lower figure.
