Rheumatoid arthritis is an autoimmune disorder that affects millions of people globally. Joint pain, inflammation, fatigue, anemia, and malaise are the frequent symptoms of this disorder.  So how can we treat this? Well, since this disorder cannot be completely cured, we can only try to reduce the symptoms. For this, immunosuppressive agents and anti-inflammatory drugs are frequently used. But these again have their side effects by altering the immunity of the individual.

Then, what exactly is safe? Should we shift over to herbs for treatment? Despite being unbelievable, a wide variety of potent herbal drugs do exist to treat rheumatoid arthritis. Now, let’s look into two of the most popularly prescribed natural anti-rheumatics.

Distribution:

This plant is native to the arid zones of Africa like Kenya, Ethiopia, and Zimbabwe. However, it is also cultivated in the subtropical regions of India.

Organoleptic evaluation:

Since the active constituent occurs in the form of a gum-resin, evaluation of its characters are done as follows:

  • Brown to pale yellow color
  • Aromatic and balsamic odor
  • Characteristic bitter taste
  • Appears as agglomerated tears that are brittle and have a waxy surface
  • On trituration with water, a white emulsion is formed

Chemical constituents:

It contains steroids, diterpenoids, carbohydrates and aliphatic esters. The therapeutically active steroids are Z-Guggulosterone, E-Guggulosterone and guggulsterone-I, II, III.

Chemical test for guggul:

Add acetic anhydride and sulphuric acid to the ethyl acetate extract of the drug. Green color develops at the junction of the two sterols.

  • The corms are ovate and have a short fracture on its surface

Chemical constituents:

Amino alkaloids are the main components. Colchicine and demecolcine are predominantly found in the seeds and corms.

Active Drug (colchicine) + 70% sulphuric acid, turns yellow, that is the chemical test.

Uses:

  • Anti-rheumatic
