Alizea, I also found a complementary article from Better Nutrition magazine. I used to buy every issue, ten years ago

Three texts form the pillars of classical Ayurvedic science, which has its roots in the country we now know as India: Charaka's Charaka Samhita (c. B.C. 700), the first, fundamental medical text; Susruta's Susruta Samhita (c. B.C. 600), which attempted to amass the whole of medical knowledge, with a special focus on surgery; and the two-volume tome consisting of the Astanga Samgraha and the Astanga Hridaya (c. 130-200 A.D.), written by Vagbhata the Elder and Vagbhata the Younger, which synthesized the works of Charaka and Susruta and summarized the eight parts of Ayurveda in prose and verse.
The first two pillars of Ayurveda describe the anti-rheumatic (antiarthritis) activity of guggals, which are gum resins of trees.
From traditional Ayurvedic texts to modern medicinal use
In addition to use for arthritis, this gummy resin (called "Salai guggal" in the vernacular) is also mentioned in traditional Ayurvedic texts as a remedy for diarrhea, dysentery, ringworm, boils, fevers (antipyretic), skin and blood diseases, cardiovascular diseases, mouth sores, vaginal discharges, ...... hair loss, jaundice, hemorrhoids, syphilitic diseases, irregular menses and to stimulate the liver.
Modern medicine and pharmacology point to Boswellia serrata's use as an anti-arthritic, anti-inflammatory, antihyperlipidemic (controls blood lipids), antiatherosclerotic (anti-coronary plaque), analgesic (pain-reliever) and hepatoprotective (protects the liver).
Anti-arthritis. Its anti-inflammatory and anti-arthritic activities have been mainly attributed to a component in the resin containing [beta]-boswellic acid.
Salai guggal has been studied by India's Regional Research Laboratory (Department of Pharmacology), located in Jammu Tawi (M.L. Sharma, et al., International Journal of Immunopharmacology, 11 (6):647-652, 1989).
This research has implicated a beneficial role for the resin in the treatment of osteoarthritis, soft-tissue rheumatism, low-back pain, gout and rheumatoid arthritis. Although rheumatoid arthritis is a crippling disease causing great physical suffering, it is possible to alleviate physical pain, increase movement (mobility) and prevent further tissue injury through proper treatment.
The standard drugs for the treatment of this condition cause undesirable side effects, including gastric irritation.
Treatment with Boswellia serrata, on the other hand, has produced excellent results. In an animal-model study by R.R. Kulkarni, et al., which appeared in the Indian Journal of Pharmacology (24:98-101, 1992), Boswellic acids "significantly reduced the infiltration of leukocytes into the knee joint," in turn significantly reducing inflammation-causing immune whited blood-cell response.
Inflammation. Boswellic acids have been shown by H.P. Ammon, et al. (Planta Medica, 57 (3):203-207, 1991) to be particularly effective in the prevention and control of inflammatory processes, which have been linked to: inflammatory joint disease, psoriasis, allergic and chronic asthma, and certain inflammatory diseases of the intestine (ulcerative colitis, Crohn's disease, and chronic hepatitis).
For pain relief, fever-reduction, cancer prevention, and more
As mentioned earlier, Boswellia serrata has been demonstrated as very effective in liver protection, exhibiting "protective effects against chemical and biological" toxins that cause inflammation and injury to the liver (Safayhi, Biochemistry and Pharmacology, 41:1536-1537, 1991); pain-relief (Menon and Kar, Planta Medica, 19:338-341, 1971); fever-reduction (Singh, Drugs of the Future, 18 (4):307-309, 1993); cancer prevention and protection (Mukherji, Indian Journal of Pharmacology, 32:48, 1970); and as an anti-bacterial (Atal, Selected Medicinal Plants of India, 1992) and anti-fungal (Garg, Indian Journal of Pharmacology, 1974).
Alcohol extracts of Boswellia serrata have been shown to significantly lower serum cholesterol and serum triglyceride levels, and reduce body-fat accumulation in hyperlipidemic animals. In fact the extracts prevented, or reversed, atherosclerosis in animals who received high-fat diets.
