Boswellia serrata is a species of tree that primarily grows in India (and also grows in the Arabian Peninsula and northeastern Africa). It produces a resin commonly known as frankincense. Biblical references to frankincense — including it being one of the gifts that the magi brought to baby Jesus — have made it popular worldwide in recent years. But it is an almost “magical” compound that has been used for thousands of years in India, China, and Greece for a treatment of inflammatory conditions.
Here is a short list of the documented activities and actions of boswellia: 
- Antihyperlipidemic (prevents elevated blood lipids)
- Analgesic (pain-relieving)
- Hepatic-protective (liver protection)
- Immune-modulatory (positively affects or strengthens the immune system)
The magi brought gifts of frankincense, myrrh, and gold; interestingly, these three items can be further identified as three powerful herbs:
- “Frankincense” is boswellia.
- “Myrrh” is almost certainly the guggul plant (Commiphora wightii).
- “Gold” is thought to be turmeric, as it was the “golden spice” and was traded more than gold during the height of the spice trade.
Today we understand the three wise men were bringing Ayurvedic medicines to baby Jesus.
Frankincense was very popular worldwide for thousands of years. During the sixteenth century in France, frankincense was used in battlefield medicine for the treatment of acute pain and swelling. Although practitioners of Ayurvedic medicine have also used Boswellia serrata for thousands of years to treat arthritis and asthma, a more recent scientific consensus appears to show that frankincense positively impacts inflammation throughout the body and is effective for a number of conditions, including osteoarthritis and rheumatoid arthritis,  inflammatory bowel disease (colitis),  colon polyps,  and lung diseases such as allergies and asthma. 
Frankincense is even the subject of increasing research on its anticancer and anti-inflammatory effects on traumatic brain injury and brain tumors. 
Frankincense is not only historically important as internal medicine, but it has been used throughout various religious communities for centuries as incense. You might have experienced frankincense at church or seen it on a televised religious broadcast. Typically, a priest or other clergy member will walk down the main aisle in the church holding a ceremonial censer of smoky incense, which burns throughout the ceremony.
Research into why frankincense has been the preferred incense used in religious practices indicates it may be due to its documented mildly psychoactive properties, which relieve a variety of stressful emotional states like anxiety and depression. The research appears to support its positive effects and its purported ability to draw people in contemplation, meditation, and prayer.
Frankincense stimulates the areas of the brain utilized in states of focus, relaxation, and calm. Therefore, the choice of frankincense might be purposeful, putting us in a calmer state, enabling us to get in touch with our inner being, and fostering a feeling of safety.  It is quite amazing how Boswellia serrata reduces not only the inflammation of the body but also that of the mind.
Thanks to the emergence of natural boswellia products, there are now more than 400 published studies on boswellia, with an average of one to two studies published weekly.
Which boswellia extract is best for me?
You might have tried supplements with boswellia before with some or limited success. This is because, as is also the case with curcumin, most boswellia is not standardized. Consumers often get boswellia extract from bark or root powder when the actual anti-inflammatory properties come from the gum resin. Thus, the part of the boswellia tree that manufacturers use makes all the clinical difference.
Without standardization of certain components (boswellic acids, AKBBA, polysaccharides, etc.), the effectiveness of a boswellia supplement can vary from batch to batch, bottle to bottle, manufacturer to manufacturer, season to season, and species to species. Beware of products on the market that are using other parts of the boswellia plant — like the leaves and bark — since these plants are grown more for their use as an incense and not as an efficacious, potent, and pure supplement. But they can still be listed as “boswellia” on supplement bottles!
Research has now shown that certain primary components of boswellia are responsible for its health benefits. Therefore, in order to get true therapeutic value, you must ensure that you are obtaining those components. Various types of boswellia have been shown to have more or greater benefits than others, with Boswellia serrata leading the research. 
Let me help educate you on what to look for when it comes to a boswellia product.
First, look to see if it is standardized to a certain amount of boswellic acids. Boswellic acids exhibit anti-inflammatory, analgesic, and antiarthritic activities through a unique 5-lipoxygenase (5-LOX) and human leukocyte elastase (HLE) inhibition mechanism. These acids are crucial to creating an effective boswellia product.
Boswellic acids also inhibit the activation of NF-kB (see figure below) and, consequently, downregulate TNF-alpha and decrease the pro-inflammatory cytokines IL-1, IL-2, IL-4, IL-6, IFN-gamma, and LTB4.  This means that boswellia helps the lower various inflammatory markers involved in many diseases. Boswellia has recently gained significant attention due to its effect on chronic inflammatory diseases and its anticancer properties.
If a boswellia product is not standardized to contain boswellic acids, then you are not getting the full benefit from it. I would not take a boswellia product that contains no boswellic acids. In general, clinical studies have found that products standardized to contain from 30 percent to 85 percent boswellic acids are the most effective on their own. (But the results are even better when combined with other boswellia components. See below.)
Second, look for how much AKBBA (acetyl-11-keto-beta-boswellic acid) is in the product. This should also be standardized to a certain percentage (between 5 percent and 30 percent AKBBA). This component appears to be just as important in improving effectiveness as boswellic acids alone. Products standardized to have AKBBA and boswellic acids are much more effective than Boswellia serrata (extract or powder) alone.
Third, look for PS (Polysal-polysaccharide). A newly discovered part of boswellia has been named a Polysal (PS) fraction. In Bosmeric-SR, this Polysal fraction is called Boswellin PS. It is the new benchmark for boswellia supplements as it contains all three major components of the compound (Polysal, AKBBA, and boswellic acids).
Without all three of these components, you simply aren’t getting what your boswellia product is promising.
Boswellia serrata-Boswellin PS: The new gold standard
Boswellin PS is the new gold standard for boswellia. In addition to its documented anti-inflammatory effects, this combination of the three critical compounds at specific potencies has been shown to be more readily and more quickly absorbed. Boswellin PS contains the key polysaccharide fraction Polysal that improves therapeutic benefits and increases the absorption and efficacy of both the boswellic acids and AKBBA.  Studies have been conducted to see how much of each of these main components one needs to maximize the anti-inflammatory benefits of boswellia.
In developing Bosmeric-SR, I intended to create a full-spectrum anti-inflammatory activity that has an immediate onset of action (water soluble) and a sustained-release effect that lasts more than eight hours. Boswellin PS gives us a clinically significant synergistic effect from a patented compound. Boswellin PS contains only clinically tested, specific dosages of Polysal, boswellic acids, and AKBBA, providing for maximum clinical benefits every time.
Once an ingredient has shown promise, most companies will try to cram the highest dose possible into their supplements. For example, some companies use only AKBBA at 90 percent concentration, with no boswellic acids or Polysal. This type of “more is better” approach, which I consider to be the general pharmaceutical approach, does not necessarily translate into better results. Scientific data has shown that synergistic compounds — not a “scorched earth” approach that bombards the body with high doses — appear to have the most beneficial effects.
The careful scientific investigation into each of the three important synergistic components of boswellia has detailed the specific ratios that provide the greatest anti-inflammatory effects. Bosmeric-SR uses these ratios. When it comes to a boswellia product, high concentrations of these three ingredients matter less than specific potencies in the right combination. Bosmeric-SR provides just that.
How much Boswellin PS should I take?
If you take a product that is standardized to have at least 65 percent boswellic acids and 10 percent AKBBA, then I recommend 500 mg twice daily with food. But if you take Bosmeric-SR, which contains the patented components of boswellia in the most effective ratios (Boswellin PS), then you need to take only 200-400 mg (that’s one to two caplets of Bosmeric-SR) twice daily with food. For those with chronic or severe health conditions such as cancer, 2 caplets three times daily with food is recommended to obtain 24 hours of inflammation support. Again, with the synergistic and enhancing benefits of curcuminoids (combined additionally with ginger and black pepper), Bosmeric-SR is more effective than even boswellia products that may offer higher concentrations of AKBBA or boswellic acids alone.
