According to certain traditional texts, turmeric, or the rhizome of Curcuma longa L. (Zingiberaceae), is also referred to as haldi in Hindi. The Indian subcontinent is commonly used as a spice and food colouring. It has historically been used to treat a wide range of conditions about the gastrointestinal tract, skin, and lungs as well as liver, wounds, and sprains. A major study over the last 50 years indicates that curcumin is responsible for most of the activities associated with turmeric. The rhizome of Curcuma longa has been shown to contain curcuminoids, which include curcumin, desmethoxycurcumin, bis-desmethoxycurcumin, volatile oils (turmerone and zingiberene), sugars, proteins, and resins. The proposed goal of this effort was to standardize the manufactured and marketed product and create a w/o type cream with turmeric as the primary ingredient. In the nations where it originated, turmeric is widely used for several purposes, such as food colouring, spice, and Indian traditional medicine to cure a variety of ailments. In one way or another, it is utilized in Hindu religious rites as well as the textile and pharmaceutical sectors. It is used in modern traditional Indian medicine to treat rheumatism, sinusitis, cough, diabetic wounds, hepatic problems, and biliary disorders. It is described as a carminative and aromatic stimulant in ancient Hindu literature. Applying a localized mixture of slaked lime powder and turmeric powder to the affected area helps relieve sprains and swelling brought on by injuries. The plant family Zingiberaceae includes ginger (Zingiber officinal Rosc.). It was first utilized as a spice and condiment to enhance the flavor of food in numerous places, but it originated in Southeast Asia. In addition, traditional herbal therapy has made use of the rhizome of ginger. Ginger's rich phytochemistry is thought to be responsible for its health-promoting properties dividing fresh ginger into two broad categories: volatiles and non-volatiles. Ginger's unique flavor and scent are attributed to volatiles such as monoterpenoid hydrocarbons and sesquiterpene. Conversely, gingerols, shogaols, parasols, and zingerones are examples of non-volatile pungent chemicals. Ginger (Zingiber officinale) rhizomes have been used for ages as a spice in cookery and as a conventional medicine. Scientific studies have demonstrated the anti-inflammatory, hypolipidemic, antidiabetic, immune-modulatory, anticancer, antiapoptotic, and anticoagulant properties of ginger. Moreover, the antifungal properties of pharmaceuticals such as fluconazole are reinforced by ginger extracts, which inhibit the growth of biofilms by a variety of pathogenic bacteria and are very successful in treating diseases caused by drug-resistant pathogens. Originating in the Mediterranean mountain regions, lavender is one of the most widely used plants worldwide. Within the Lamiaceae family, the genus Lavandula has more than thirty species. The most widely grown species is Lavandula angustifolia Mill. (narrow-leaved lavender), Lavandula stoechas (French lavender), and Lavandula latifolia (broad-leaved lavender). The Latin verb lavare, which means "to wash," is the source of its common name. Garden lavender, often known as narrow-leaved lavender (Lavandula angustifolia, originally L. officinalis Chaix or L. vera), is the most valued genus among all the Lavender plants in terms of its distinct biological activity. Flowers and the upper growth of narrow-leaved lavender are used to make lavender oil. Flowers provide the majority of the therapeutic raw material, with about 3% coming from the essential oil. Comparable components, albeit in varying amounts, are present in the essential oils of the genus Lavender. Factors such as variety, growth circumstances, and place of origin affect the essential oil’s composition and quality. They are primarily classified as phenolic chemicals (flavonoids, phenolic acids, coumarin, tannins) and terpenoid compounds (monoterpenes, triterpenes, sesquiterpenes). Aloe vera, also known as Aloe barbadensis Miller, is a perennial succulent plant that is a member of the Liliaceae family. Gel and latex are two compounds that come from the plant. Squeezing the leaves releases the mucilaginous gel that is contained in the parenchymatous cells of the leaf pulp. Aloe latex, a yellow-bitter juice, is produced by the plant's peripheral bundle sheath cells and mostly contains anthraquinones and their derivatives, such as aloesin, oleoresin A, aloemodin, and barbalus (aloin A). Aloe latex on a dry-weight basis also includes a large quantity of ash, essential oil, and resin that is insoluble in acid. Polysaccharides, particularly ace Mannan, are the major components of the A. Vera gel. The ingestion of A. Vera leaf formulations have been demonstrated to have anti-arthritic and antirheumatoid, anticancer, and antidiabetic activities, despite the scientific literature providing minimal evidence to support claims on the systemic effects of A. Vera. Topically, A. Vera gel is used for a variety of therapeutic applications, such as treating heat injury and chronic wounds, reducing inflammation, treating mouth ulcers, preventing UV-induced immunosuppression, and treating psoriasis and skin infections. Well-designed scientific research is necessary to address this problem, particularly concerning sunburn treatment, since published results on the effects of Aloe vera gel on skin disorders are inconsistent.

The availability of herbal cosmetics has led to a primary increase in demand for cosmetics. Furthermore, it supplies the skin with essential nutrients and moisture. The herbal cream is just an emulsion of water and oil. Turmeric, ginger, lavender, and aloe Vera are among the natural ingredients used to prepare the herbal lotion. The specific qualities of each ingredient determine which one is used. Aloe vera works as an anti-acne and moisturizer. An Asian beauty product called turmeric is useful for giving the skin a golden glow. As a natural defensive reaction to tissue damage brought on by harmful chemicals, microbes, or physical trauma, inflammation occurs. Throughout human history, medicinal plants have been identified and utilized. In addition to carrying out essential biological tasks and protecting humans from predators like insects, fungi, and other microorganisms, plants can synthesize a vast array of chemical substances.

Cultivation  

Turmeric: -

Soil properties: This crop can be cultivated on sandy soil having a good facility or loamy soil having enough humus content. To obtain a high yield of turmeric, the rhizome formation must be of high quality and can be achieved easily in soil having pulverized tilth

(Table 1)

Land preparation: The minimum tillage operation results are good for this crop. In the case of an irrigated crop system, the ridges and furrows are prepared for turmeric cultivation and the crop is sown on the ridges with shallow pits and the proper spacing is provided. Soil solarization is also used.

Ginger

It is usually cultivated vegetation, meaning the pieces of rhizome are planted in the soil and each sprouts to form a new plant. Modern micropropagation is also being used where new plants are cloned from cells taken from a single plant. The propagation through rhizome cuttings includes small bits of rhizome; each containing a bud is planted in holes or trenches 10–15cm deep and about 30cm apart during the months from March to May. The plants produce aerial shoots which are dried after flowering and fruiting in about 8–10 months. Though ginger requires ample rainfall, there should not be any waterlogging at any time; otherwise, it may result in rotting.

Ginger, like turmeric, can grow under both irrigated and rain-fed conditions. The best time for planting is just after the pre-monsoon showers. In case there are no pre-monsoon showers, then irrigation is necessary. Else the seed rhizomes would dry up.     

Aloe vera: -

Aloe is found as a wild herb along the coast of South India. It is under cultivation in fairly large areas in many parts of India, viz. Chhatisgarh, Maharashtra, Madhya Pradesh, Gujarat, etc. And also grown as an ornamental plant. It is a sure cash spinner and progressive farmers can go for plantation of it. Cultivation of this herb on a large scale can make India move towards the leadership in global herbal market and this will fetch India good foreign reserves as well as domestic economic prosperity. Commercial cultivation of Aloe has been started in many parts of India. They can be grown in deserts and other dry situations. They flourish in a variety of climates and even on the poorest of soils but need protection from frost. Soil: Naturally occurs in the driest and poorest soils and can be grown in a variety of soils. But the most ideal soil for it is sandy loam which is slightly alkaline with a pH up to 8.5. The root system of this plant is shallow and does not penetrate deep into the soil. However, water-logged soil is unsuitable.

Reported Activities from Modern Literature

1. B. CHENGAIAH et, al, -In addition to their ability to dye, natural dyes provide a variety of therapeutic benefits. Thankfully, people's understanding of natural dyes and plants that provide dye is growing these days. Owing to their non-toxic characteristics, many food goods and the pharmaceutical sector employ natural hues, which have more therapeutic properties and fewer adverse effects. Despite having abundant plant resources, very little of them have been used up to this point in time. More thorough research and scientific studies are required to determine the true potential and supply of naturally occurring dye-producing resources, which are in high demand for the therapeutic formulations of naturally occurring medications used in the pharmaceutical industry. In conclusion, the pharmaceutical industry must continue to grow to create safe, therapeutically effective pharmaceutical formulations and dosage forms using natural plant pigments. This requires appropriate procedures, documentation, and characterization of dye-producing plants.
2. Roshan Prasad Yadav et, al -Naturally occurring dyes possess a multitude of medical effects in addition to their ability to dye. Thankfully, more and more people are becoming aware of natural dyes and plants that may produce dyes nowadays. Considering that they are non-toxic, less natural colors with higher therapeutic properties and fewer adverse effects are employed in everyday food goods and the pharmaceutical business. Even though there are many plant resources in the world, very little of them have been used up to this point. To evaluate the true potential and availability of naturally occurring dye-producing resources that are in high demand in the therapeutic formulations of natural pharmaceuticals sold commercially, more thorough studies and scientific investigations are required. To incorporate natural plant pigments into pharmaceutical formulations or dosage forms that are safe for use, the pharmaceutical industry must continue to refine its processes, documentation, and characterization of dye-yielding plants.
3. Nafiseh Shokri Mashhadi et, al -Ginger is widely recognized for its health-promoting properties. Through immunonutrition and anti-inflammatory reactions, it can treat a variety of illnesses. Ginger has an anti-inflammatory impact, which helps lessen muscle soreness after strenuous exercise. Similar to other plants, ginger has a well-established ability to fight cancer. Its active components, such as parasols, shogaol, and gingerols, are useful compounds that can stop the spread of cancer, angiogenesis, and metastasis, as well as induce apoptosis and arrest the cell cycle. In addition to these, it enhances the health of the gastrointestinal system, diabetes, and cardiovascular conditions.
4. Shivraj Hariram Nile et, al -Our findings imply that the active ingredients 6-gingerol (6G), 6-shogaol (6S), and 6-paradol (6P), as well as the ginger ethyl acetate and water extracts, have potent anti-inflammatory, antioxidant, and xanthine oxidase inhibitory properties. For them to be classified as an agent for treatment against different diseases and disorders linked to oxidative stress, xanthine oxidase, and free radicals, more in vivo and clinical research is necessary. This investigation offers a scientific.
5. Ma?gorzata Miastkowska et, al -According to earlier accounts, lavender angustifolia essential oil can heal wounds. This is where we propose that the origin and growth circumstances of the plant, as well as the composition of the oil, determine the mode of action and efficacy of lavender oil. Human monocyte-derived macrophages and epithelial cells (HaCaT human keratinocyte line) were the subjects of the in vitro investigations that were reported. As a result of co-stimulating cells with bacterial lipopolysaccharide (LPS), keratinocyte synthesis of IL-6 and IL-8 was shown to be concentration-dependently elevated. The adjustment of the inflammatory response occurred when lavender oil was present in the LPS-stimulated macrophages, limiting the generation of TNF-? in MDM. It was also shown that the VEGF cytokine enhanced the pro-regenerative response of HaCaT cells.
6. Tomasz Kantyka et, al -Lavender oil has been found to have a strong potential to limit the inflammatory stimulation of immune system cells and to enhance the local, tissue-derived proinflammatory and pro-regenerative response. The in vitro cell models showed significantly better performance for the in-house preparation of lavender oil. Due to a drop in linalool acetate and a rise in Lavandula acetate in the in-house formulation, this effect might be explained. It will take more research to confirm the significance of each component of lavender oil and to define the role of inflammatory regulation and VEGF stimulation in the oil’s support of wound healing.
7. J. Reuter et, al -Compared to the placebo gel containing 1% hydrocortisone, the A. Vera gel (97.5%) in this trial showed some stronger anti-inflammatory benefits after 48 hours. An inflammatory skin condition like UV-induced erythema may benefit from topical treatment with the A. Vera gel is examined here.
8. A Jocher et, al -A common ingredient in calming skin care products like after-sun lotions is aloe vera, a natural substance. In this investigation, our goal was to determine whether a highly concentrated A. Vera gel could reduce inflammation in vivo using the UV erythema test.
9. Somnath S Davkhar et, al -The produced herbal cream shields the skin from a variety of skin problems and has the best qualities and nutritional value while using minimal chemicals. This cream is very inexpensive because it was made with basic materials and a basic preparation technique. The herbal cosmetic mixture can be applied as a barrier to protect skin and is safe to use. According to the findings of various cream experiments, the formulation could be applied topically to shield skin from harm. Since they are thought to be safer and have fewer negative effects than synthetic ones, natural therapies are more widely accepted. There will be more investigation to verify the formulation’s synergistic effect scientifically.
10. Sailor Niyanta et, al -The physicochemical parameters of the turmeric cream formulation provide good results, matching those of the marketed formulation. Based on the carrageenan-induced rat paw edema method, the release of active components is effective in formulations intended to reduce inflammation. Future clinical research may be necessary to ensure its appropriate use.
11. Patel Ritesh et, al -Turmeric, or Curcuma longa, is a Zingiberaceae plant whose rhizomes are used to manufacture the spice. Curcumin is widely recognized for its ability to reduce inflammation and safeguard the skin. In natural herbal remedies, curcumin has long been used to treat inflammation and skin infections. This study aims to create an anti-inflammatory cream with a turmeric foundation. The main emulsion process was used to manufacture the herbal cream. The turmeric cream was subjected to a variety of physiochemical tests, including ones measuring pH, drug content, spreadability, viscosity, appearance, homogeneity, grittiness, and anti-inflammatory activity. The results of the study on several physicochemical characteristics were found to be acceptable and in line with turmeric cream that is sold commercially.

Inflammation

Inflammation may be indicated by a wound that hurts, swells, and turns red. The body’s immune system’s reaction to an irritant is, in general, what causes inflammation. If you have a splinter in your finger, for example, the irritant may not be a bacterium but something foreign.[9]

Anti-inflammatory

Muscle or joint discomfort can be brought on by inflammation. Pain and swelling brought on by a variety of illnesses and injuries can be lessened using topical anti-inflammatory treatments. As common topical anti-inflammatory drugs, Voltaren (diclofenac) gel, capsaicin cream, and menthol cream are used. Creams for inflammation can provide advantages comparable to those of oral medications when taken as prescribed. Their side effects also seem to be less common.[8]

Types Of Anti-inflammatories

1. Nonselective COX inhibitors (traditional NSAIDs)

1) Salicylates – Aspirin

2) Propionic acid derivative – Ibuprofen, ketoprofen

3)  Anthranilic acid derivative – Mefenamic acid

4) Aryl-acetic acid derivative- Diclofenac, Aceclofenac

5) Oxicam derivative – Piroxicam

6) Pyrrolo-pyrrolo derivative – Ketorolac

7) Indole derivative – Indomethacin

8) Pyrazolone derivative – Phenylbutazone, Oxyphenbutazone

2. Preferential COX-2 inhibitor

Nimesulide, Meloxicam, Nabumeton

3. Selective COX-2 inhibitor

       Celecoxib, Etoricoxib

4. Analgesic antipyretics with poor anti-inflammatory action

1. Para aminophenol derivative – Paracetamol
2. Pyrazalone derivative – Metamizole, Propyphenazone
3. Benzoxazocine derivative – Nefopam

Types Of Inflammation

1. Acute inflammation

Your body's reaction to an unexpected injury or sickness is this. When an injury occurs, such as a cut on your finger, or an infection occurs, inflammatory cells move to the area and initiate healing. There can be unexpected, and typically transient, inflammation brought on by infections in many bodily areas. Inflammation of the throat can be brought on, for instance, by viral or bacterial illnesses such as strep throat. Inflammation of the small intestine (enteritis) can be brought on by separate bacterial and viral infections. Depending on your health, the duration of acute inflammation might range from a few hours to many days.

2. Chronic inflammation

This occurs when there is no threat, but your body still produces inflammatory cells. Inflammatory cells and chemicals, for instance, assault joint tissues in rheumatoid arthritis. Your joints may sustain significant damage as a result of this intermittent inflammation. Procedures that should safeguard your body can wind up harming it when there is persistent inflammation. Months or years may pass during a period of chronic inflammation. It might get better for periods and then worse for others.

Symptoms of Acute and Chronic Inflammation

       
           
       
Fig no-05 Symptoms of Acute and Chronic Inflammation

Risk Factors of anti-inflammatory

• Raised liver enzymes (detected by a blood test, this is more commonly associated with diclofenac than other NSAIDs)
• diarrhoea.
• headache.
• dizziness.
• salt and fluid retention.
• high blood pressure.

How do anti-inflammatory creams work?

Depending on the drug. All anti-inflammatory lotions, however, must first be absorbed through the skin. At this point, the drug begins to ease pain in the surrounding muscles or joints. This may occur when the drug is distributed very little or not throughout the body.

How to apply anti-inflammatory creams

Applying anti-inflammatory treatments to the damaged area of your body's healthy skin is a good idea. The steps for using these topical medications are described below:

1. Before applying the drug, wash your hands with soap and water.
2. Cream should be applied sparingly to the sore spot. Measure out the right dosage of medication using the dosing card, if one is provided.
3. When you can no longer see the drug, carefully rub it into your skin.
4. The majority of products should only be used up to four times each day, though you can repeat doses as necessary. Be sure to adhere to the precise usage guidelines provided by your product.
5. To ensure that the drug is properly absorbed by your skin, wait at least one hour before taking a shower or cleaning the region.
6. Repeatedly wash your hands following each application. This is particularly crucial after using a cream containing capsaicin, which may burn.

It's crucial to remember that open wounds or skin that are inflamed or broken shouldn't be treated with these lotions. And if there is any pharmaceutical residue on your hands, refrain from touching your mouth, nose, or eyes.

Treatment Of Anti-inflammatory

Aspirin

       
           
       
The enzyme phospholipase 2 is present in every cell in our body and is triggered by infections or damage to the cell. Membrane lipids are converted to arachidonic acid by it, and prostaglandins are subsequently produced by the enzyme cox1/2. These prostaglandins are responsible for both pain and inflammation. They do this by stimulating the nerve endings of the pain nerves and widening blood vessels, which draws white blood cells to the site of injury.

Evaluation of Cream

1. Physical evaluation:

Color, smell, texture, and condition were noted during the physical assessment.

2. Irritancy:

Mark an area of 1 cm2 on the left dorsal surface. Following the designated area's application of the cream, the time was noted. It is then assessed for erythema, oedema, and irritation, if present, for a maximum of 24 hours before being reported.

3. Washability:

The hand was given a small amount of cream, and to see if it could be cleaned, tap water was used.

4. Spreadability:

It was decided to put cream in between a pair of glass slides. They were compressed to a set force, and the length of time it took for a slide to separate from the other was recorded. The surplus product that remained on the slides was scraped off once the weight was removed. It fell off with ease thanks to the weight force associated to the upper slide.

Spread ability= m × l/t
