represent the furthest penetrability barrier for a diversity of antimicrobials which are
the main cause of the remarkably leisurely influx of lipophilic molecule in
gram-negative bacteria. Instead, porin proteins entrenched in the superficial sheath
signify the main channels for entry of molecules inside the cells of gram-negative
bacteria. Curcumin can reinstate bacterial susceptibility, impeding the development
of biofilm, and make microorganisms more sensitive to antibiotics. Accordingly, it
has been noticed that its antibacterial activity potentiated once it is allied with other
antibiotics, such as cefixime, tetracyclines, and vancomycin (Alves et al. 2018). The
antimicrobial potential of curcumin can be significantly improved by acquaintance
with light. The broad absorption range (300–500 nm) with a maximum absorption
band at 425 nm makes curcumin a potent photosensitizer, leading to the enhanced
antimicrobial potency (Nikaido 2003). Curcumin also inhibits in vitro production of
aflatoxin, it is produced by mold Aspergillus parasiticus, which may grow and
contaminate poorly preserved foods and it is a potent biological agent causing
injury to the liver.
12.3 Garlic
Garlic, i.e., Allium sativum Linn is a bulbous herb of the Alliaceae family and has
been used traditionally as a spice for thousand years and extensively used for its
medicinal properties such as antibacterial, antiviral, and antifungal properties. The
garlic plant is a bulb growing upward to 25-70 cm with hermaphrodite flowers
(Mikaili et al. 2013). Not only the root bulb of the garlic but leaves and flowers for
medicinal properties for very long. Throughout the time of pre-antibiotics, garlic
bulbs assisted as one of the chief treatment approaches for a wide-ranging illness
due to its broad-spectrum effects (Majewski 2014; Petrovska and Cekovska 2010).
Garlic was also used as a supplement nutrient, as a treatment for weakness and skin
infections. The first indication of garlic for its antimicrobial properties was reported
in France during the plague of Marseilles in 1721 when four men resorted to
consuming a mixture of macerated garlic and wine tincture known as ″vinaigre des
quatre voleurs″ to protect themselves from getting the disease that was afflicting
those around them (Harris et al. 2001). Further, around five years later the garlic
was utilized at a mass rate by the Egyptians to treat the abnormal growth and also
with the circulation problems. Then, North Americans started utilizing this for the
treatment of symptoms like flu. Therefore, these shreds of evidence show that it is a
prime notification toward the accurate research in the field of science before the
development of modern universities and they also develop the attitude to the scientist around the globe. Garlic has a minor, faint smell up until it has been unpeeled.
After it is peeled, cut up, or meshed, it instantly activates to feast a strong smell,
glycosides. The distillation of garlic with water vapor yields etheric oil with its
distinctive sharp smell. The examination of the chemical content of that garlic oil
confirmed the presence of few aliphatic unsaturated sulfur compounds (Petrovska
and Cekovska 2010). Even in dilution of allicin 1: 85,000 to 1: 250,000, allicin
