Kalamegha: The king of bitter


Kalamegha or Bhunimba botanically known as Andrographis paniculata is a small annual herbaceous plant. Kalamegha means dark cloud or Bhunimb means Neem of the ground, as the bitter taste of the small annual herb Kalamegha, is similar to the bitter taste of a large Neem tree. Kalamegha is native to India and Sri Lanka but widely cultivated in southeast Asia, and South Asia to treat various disorders, especially infection. In Malaysia, Kalamegha is used to treat hypertension and diabetes. In India and China, Kalamegha is traditionally used to treat fever, cold, laryngitis, and various infectious diseases. In Classical Ayurvedic texts, Kalamegha is Tikta (bitter), in taste with hot potency, and Katu Vipaka acts as Kapha Pitta Shamaka. It is used to treat Jwara, Agnimandya, Yakrit Vikara, Kustha, etc. Recent research proved that Kalamegha contains two crystalline form alkaloids including Kalmeghin, lactone, andrographolide, andrographide, tannin, and volatile oil in little quantities. The ash obtained from the plant had sodium chloride and potassium salts. Due to these active ingredients, Kalamegha exhibits multiple pharmacological properties like hypotensive activity, anticancer activity, anti-tumor activity, hypoglycemic activity, anti-inflammatory, antipyretic, hepato- protective, antithrombotic activity, etc.

Kalamegha’s description in Brihtrayi as Bhunimba

It has been noted that Andrographis paniculata is popularly known as Bhunimba in M. P. and Nagpur area and as Chirayata in the Bihar forests. Kalamegha is another common name given to this plant. It indicates its use in place of Kiratatikta for a long time. Its use in liver complaints is also well known. It has also been identified with Yavatikta of the texts. Do all these facts hint at the possibility of Andrographis being Bhunimba of the texts with Yavatikta as its synonym? If so, it will cease to be a synonym of Kiratatikta and be treated as an independent drug with Bhunimba as its original name.

Kalamegha’s description in Brihtrayi as Yavatikta (controversy)

At present, Yavatikta is considered to be what is known as Kalamegha (Andrographis paniculata). It has been mentioned to be a synonym of Sankhini in C. S. Ka. 11. 2, but in S. S. Su. 45. 124- 125 the oils of Sankhini and Yavatikta have been described separately as different substances. Dalhana in his comments on Yavatikta states that it is a plant growing in the barley fields and has seven or eight leaves. He might likely have referred to another plant, Canscora decussata. This is slightly bitter in taste, laxative and wrongly considered by many as Sankhini or Sankhapuspi due to its reported property of being a nervine tonic. It is, therefore, felt that this might have been the original Yavatikta but later on Andrographis was accepted as another alternative source of Yavatikta and none of these two are either Sankhini or Sankhapuspi. Thus, Canscora may be accepted as Yavatikta and Andrographis as Bhumimba.

Kalamegha’s description in Brihtrayi as Kirata, Kirata Tikta (Controversy)

In reality Kirata Tikata is Swertia chirata. The substitute of this by other species of Swertia and by Andrographis paniculata is generally practiced to such an extent that they are being passed on in the drug market under the names of Chiryata and Bhunimba.

Kalamegha’s description in Brihtrayi as Sankhini (Controversy)

The purgative (Bhedaniya) action (C. S. Su. 4/ 4) given so much emphasis combined with its property of a nervine tonic (Medhya) in the literature does not permit Canscora or Andrographis to be accepted as Sankhini. Dalhana and Chakra in their comments have mentioned Svetabunha which is Colonyction muricatum G. Don. ( Koudena). Its seeds are used as an adulterant of Kaladana- (Ipomoea hederacea Linn.). It is also to be noted that the reasons which have tempted an important section of the South Indian Vaidyas to accept Clitoria as Sankhapuspi may also be used to label it as Sankhini. This may also be named Sirisa Bija with seeds resembling those of Sirisha.

Historical background of Kalamegha

It is an annual erect herb growing up to 1 m high and bearing white flowers with purple stripes. It is commonly seen in most parts of India, It is now very clear that Kiratatikta (S. chirata) is different from Kalamegha (A. paniculata). Bapalal and Thakurji think that Yavatikta is A. paniculata. Keeping other controversies aside, one should realize the importance of Andrographis as a potent hepatoprotective and antifebrile agent.

Controversial Studies regarding Kalamegha

The identity of Kalamegha and Kiratatikta has always been Controversial always. The problem is because of the common two plants i.e., ‘Bhunimba’. It is now clearly identified that the former is Andrographis paniculata and the latter is S. chirata respectively. Sivadatta kosha described Kirata tikta as a plant whose leaves are similar to Bhringaraja and possess golden yellow flowers. It is commonly found in mountain areas (Himalayas). It is used traditionally in the management of fever and wounds.

Recent research on Andrographis paniculata

  • Enmozhi SK, Raja K, Sebastine I, Joseph J. Andrographolide as a potential inhibitor of SARS- CoV- 2 main protease: an in-silico approach. J Biomol Struct Dyn. 2021 Jun; 39 (9): 3092- 3098. doi: 10. 1080/ 07391102. 2020. 1760136. Epub 2020 May 5. PMID: 32329419; PMCID: PMC7212536. SARS- CoV- 2 viruses which caused the global pandemic the Coronavirus Disease- 2019 (COVID-2019) has infected about 1,203,959 patients and brought forth a death rate of about 64,788 among 206 countries as mentioned by WHO in April 2020. Clinical trials are underway for Remdesivir, an investigational antiviral drug from Gilead Sciences. Antimalarial drugs such as Chloroquine and Hydroxychloroquine derivatives are being used in emergency cases; however, they are not suitable for patients with conditions like diabetes, hypertension, and cardiac issues. The lack of availability of approved treatment for this disease calls forth the scientific community to find novel compounds with the ability to treat it. This paper evaluates the compound Andrographolide from Andrographis paniculata as a potential inhibitor of the main protease of SARS-COV-2 (Mpro) through in silico studies such as molecular docking, target analysis, toxicity prediction, and ADME prediction. Andrographolide was docked successfully in the binding site of SARS- CoV- 2 Mpro. Computational approaches also predict this molecule to have good solubility, pharmacodynamic properties, and target accuracy. This molecule also obeys Lipinski’s rule, which makes it a promising compound to pursue further biochemical and cell-based assays to explore its potential for use against COVID-19.
  • The current investigation aimed to determine the hepato- protective role of silver nanoparticles (AgNPs) synthesized rapidly using Andrographis paniculata. A low dose (25 mg/ kg BW) was effective in the revival of all biological parameters to near normal in all intoxicated groups indicating the curing effects on CCl4-induced liver injury.
