Seed oils and your SKIN

Dr. Weeks’ Comment: Hundreds of people report to me that when they rub whole crushed organic non-GMO seeds on their skin, the seed oils (being so rich in unadulterated omega 6 fatty acids) penetrate through the skin layers and displace old, oxidized and inflamed skin while creating healthy, smooth nourished skin. They look younger! But now we see what Seeds of Eden can do for skin cancers!   Remember what Paracelsus taught in the 1400’s: “Nature provides the cure, the role of the doctor is to discover it.” Eat the seeds!

Ahmad A1, Husain A, Mujeeb M, Khan SA, Najmi AK, Siddique NA, Damanhouri ZA, Anwar F.



Nigella sativa (N. sativa) (Family Ranunculaceae) is a widely used medicinal plant throughout the world. It is very popular in various traditional systems of medicine like Unani and Tibb, Ayurveda and Siddha. Seeds and oil have a long history of folklore usage in various systems of medicines and food. The seeds of N. sativa have been widely used in the treatment of different diseases and ailments. In Islamic literature, it is considered as one of the greatest forms of healing medicine. It has been recommended for using on regular basis in Tibb-e-Nabwi (Prophetic Medicine). It has been widely used as antihypertensive, liver tonics, diuretics, digestive, anti-diarrheal, appetite stimulant, analgesics, anti-bacterial and in skin disorders. Extensive studies on N. sativa have been carried out by various researchers and a wide spectrum of its pharmacological actions have been explored which may include antidiabetic, anticancer, immunomodulator, analgesic, antimicrobial, anti-inflammatory, spasmolytic, bronchodilator, hepato-protective, renal protective, gastro-protective, antioxidant properties, etc. Due to its miraculous power of healing, N. sativa has got the place among the top ranked evidence based herbal medicines. This is also revealed that most of the therapeutic properties of this plant are due to the presence of thymoquinone which is major bioactive component of the essential oil. The present review is an effort to provide a detailed survey of the literature on scientific researches of pharmacognostical characteristics, chemical composition and pharmacological activities of the seeds of this plant.

Thymoquinone suppresses metastasis of melanoma cells by inhibition of NLRP3 inflammasome.

Ahmad I1, Muneer KM, Tamimi IA, Chang ME, Ata MO, Yusuf N.



The inflammasome is a multi-protein complex which when activated regulates caspase-1 activation and IL-1β and IL-18 secretion. The NLRP3 (NACHT, LRR, and pyrin domain-containing protein 3) inflammasome is constitutively assembled and activated in human melanoma cells. We have examined the inhibitory effect of thymoquinone (2-isopropyl-5-methylbenzo-1,4-quinone), a major ingredient of black seed obtained from the plant Nigella sativa on metastatic human (A375) and mouse (B16F10) melanoma cell lines. We have assessed whether thymoquinone inhibits metastasis of melanoma cells by targeting NLRP3 subunit of inflammasomes. Using an in vitro cell migration assay, we found that thymoquinone inhibited the migration of both human and mouse melanoma cells. The inhibitory effect of thymoquinone on metastasis was also observed in vivo in B16F10 mouse melanoma model. The inhibition of migration of melanoma cells by thymoquinone was accompanied by a decrease in expression of NLRP3 inflammasome resulting in decrease in proteolytic cleavage of caspase-1. Inactivation of caspase-1 by thymoquinone resulted in inhibition of IL-1β and IL-18. Treatment of mouse melanoma cells with thymoquinone also inhibited NF-κB activity. Furthermore, inhibition of reactive oxygen species (ROS) by thymoquinone resulted in partial inactivation of NLRP3 inflammasome. Thus, thymoquinone exerts its inhibitory effect on migration of human and mouse melanoma cells by inhibition of NLRP3 inflammasome. Thus, our results indicate that thymoquinone can be a potential immunotherapeutic agent not only as an adjuvant therapy for melanoma, but also, in the control and prevention of metastatic melanoma.

Antineoplastic and apoptotic potential of traditional medicines thymoquinone and diosgenin in squamous cell carcinoma.

Das S1, Dey KK, Dey G, Pal I, Majumder A, MaitiChoudhury S, kundu SC,




Thymoquinone (TQ) and diosgenin (DG), the active ingredients obtained from black cumin (Nigella sativa) and fenugreek (Trigonella foenum graecum), respectively, exert potent bioactivity, including anticancer effects. This study investigated the antineoplastic activity of these agents against squamous cell carcinoma in vitro and sarcoma 180-induced tumors in vivo. TQ and DG inhibited cell proliferation and induced cytotoxicity in A431 and Hep2 cells. These agents induced apoptosis by increasing the sub-G(1) population, LIVE/DEAD cytotoxicity, chromatin condensation, DNA laddering and TUNEL-positive cells significantly (P<0.05). Increased Bax/Bcl-2 ratio, activation of caspases and cleavage of poly ADP ribose polymerase were observed in treated cells. These drugs inhibited Akt and JNK phosphorylations, thus inhibiting cell proliferation while inducing apoptosis. In combination, TQ and DG had synergistic effects, resulting in cell viability as low as 10%. In a mouse xenograft model, a combination of TQ and DG significantly (P<0.05) reduced tumor volume, mass and increased apoptosis. TQ and DG, alone and in combination, inhibit cell proliferation and induce apoptosis in squamous cell carcinoma. The combination of TQ and DG is a potential antineoplastic therapy in this common skin cancer.

Anticancer activities of Nigella sativa (black cumin).

Khan MA1, Chen HC, Tania M, Zhang DZ.



Nigella sativa has been used as traditional medicine for centuries. The crude oil and thymoquinone (TQ) extracted from its seeds and oil are effective against many diseases like cancer, cardiovascular complications, diabetes, asthma, kidney disease etc. It is effective against cancer in blood system, lung, kidney, liver, prostate, breast, cervix, skin with much safety. The molecular mechanisms behind its anticancer role is still not clearly understood, however, some studies showed that TQ has antioxidant role and improves body’s defense system, induces apoptosis and controls Akt pathway. Although the anti-cancer activity of N. sativa components was recognized thousands of years ago but proper scientific research with this important traditional medicine is a history of last 2∼3 decades. There are not so many research works done with this important traditional medicine and very few reports exist in the scientific database. In this article, we have summarized the actions of TQ and crude oil of N. sativa against different cancers with their molecular mechanisms.

Molecular pathway for thymoquinone-induced cell-cycle arrest and apoptosis in neoplastic keratinocytes.

Gali-Muhtasib HU1, Abou Kheir WG, Kheir LA, Darwiche N, Crooks PA.



Thymoquinone (TQ), the most abundant constituent in black seed, was shown to possess potent chemopreventive activities against DMBA-initiated TPA-promoted skin tumors in mice. Despite the potential interest in TQ as a skin antineoplastic agent, its mechanism of action has not been examined yet. Using primary mouse keratinocytes, papilloma (SP-1) and spindle (I7) carcinoma cells, we studied the cellular and molecular events involved in TQ’s antineoplastic activity. We show that non-cytotoxic concentrations of TQ reduce the proliferation of neoplastic keratinocytes by 50%. The sensitivity of cells to TQ treatment appears to be stage dependent such that papilloma cells are twice as sensitive to the growth inhibitory effects of TQ as the spindle cancer cells. TQ treatment of SP-1 cells induced G0/G1 cell-cycle arrest, which correlated with sharp increases in the expression of the cyclin-dependent kinase inhibitor p16 and a decrease in cyclin D1 protein expression. TQ-induced growth inhibition in I7 cells by inducing G2/M cell-cycle arrest, which was associated with an increase in the expression of the tumor suppressor protein p53 and a decrease in cyclin B1 protein. At longer times of incubation, TQ induced apoptosis in both cell lines by remarkably increasing the ratio of Bax/Bcl-2 protein expression and decreasing Bcl-xL protein. The apoptotic effects of TQ were more pronounced in SP-1 than in I7 cells. Collectively, these findings support a potential role for TQ as a chemopreventive agent, particularly at the early stages of skin tumorigenesis.
